The specific purpose of this study is to develop the numerical guide for the cost-benefit analysis of ORE ($/person-Sv reduction) to meet the criterion of ALARA in the design stage of the KNGR. In deriving the guide, the risk factor which is defined by the risk to unit collective radiation exposure dose (deaths/person-Sv) and the monetary value of human life ($/death) are required. The risk factor has been estimated from various clinical data accumulated for a number of years and continuously modified. And the monetary value of human life is usually quantified using the human capital approach. In this study, the risk to radiation exposure perceived by a group of people is investigated through an extensive poll survey conducted among university students in order to modify the existing risk factor for radiation exposure. And in evaluating the monetary value of human life, the QOL factor is introduced in order to incorporate the degree of public welfare or quality of life. As a result of study, a value within the range of 151, 000~172, 000 dollars per person-Sv reduction is recommended as the appropriate interim numerical guide for cost-benefit analysis of ORE to meet the criterion of ALARA in the design stage of the KNGR. A poll survey was also conducted in order to see whether the public acceptance cost of nuclear power should be incorporated in developing the guide, and the result of study shooed that such a cost does not need to be considered.

Consumers are not simply consuming products anymore. They now take part in developing new products. Thus, it is essential that we devise a variety of consumer-oriented marketing strategies to keep close relationships with consumers. The purposes of this study were as follows: 1) to explore the relationship between customer participation and surveys on its effect, 2) to compare groups with respect to customer participation, and 3) to see whether there is a cause-effect relationship between the customer participation and surveys on its effect. Frequency analysis, correlative analysis and discriminate analysis were used to analyze the data. The results of testing hypotheses can be summarized as follows. we find that, as for customer participation factors, there is significant relationships among survey factors including customer satisfaction, cost reduction, customers' prior occupations. The current analysis exhibits favorable results in the customer participation and such factors. The analysis shows that there is significant difference between the active groups and the passive groups in all the new product development related factors; customer satisfaction, cost reduction, customers' prior occupations. Finally, this perhaps indicates that the result of the survey depends on whether firms are positive or negative in introducing customer participation.

Independent suspension axle and final reduction gear for special-purpose vehicles such as a armored vehicles are almost imported in Germany etc. so, developing them is necessary to save cost. In severe condition (open fields, water surface driving, obstacle pass), special-purpose vehicles must work well. Drop box, axle and final reduction gear performed static analysis. We know that is possible weight reduction. The purpose of this paper is to find out the optimal shape of final reduction gear's case by means of response surface methodology. The response surface method is the statistical method which can be applied to the non-sensitivity based optimization. The response surface which is constructed by the least square method contains only the polynomial terms so that the global maximum and minimum points are easily obtained.

In this paper, the loading methods of EOTS for an exploratory developing fighter were analysed by the technical characteristics of it's operation, maintenance, engineering technology and development cost. By the analysis of operational ability evaluation, the internal type had the merits of stealth function, but the external loading type was preferable to certificate the accessibility, install/detach, compatibility and interoperability with the existing fighter aircraft. From the results of 17 items of technology and development cost evaluation, we found out that the internal type had the advantage of small sizing lightweight, but the external type was highly estimated in the field of application of domestic technology, cost reduction and technical stability for achievement of performance.

This study examines greenhouse gas reduction potentials in cement manufacturing industry of Korea. An energy system model in the MARKAL (MARKet ALlocation) modeling framework was used in order to identify appropriate energy technologies and to quantify their possible implications In terms of greenhouse gas reduction. The model is characterized as mathematical tool for the long term energy system analysis provides an useful informations on technical assessment. Four scenarios are developed that covers the ti me span from 2000 to 2020. Being technology as a fundamental driving factor of the evolution of energy systems, it is essential to study the basic mechanisms of technological change and its role in developing more efficient, productive and clean energy systems. For this reasons, the learning curves on technologies for greenhouse gas reduction is specially considered. The analysis in this study shows that it is not easy to mitigate greenhouse gas with low cost in cement manufacturing industry under the current cap and trade method of Kyoto protocol.

The cost-effective reduction of greenhouse gas(GHG) emission to avert the most severe impacts of climate change remains one of the widely accepted priorities for global action. In order to facilitate cost-effective abatement strategies, the Kyoto Protocol introduced three mechanisms, or flexible instruments, the Emissions Trading(ET), the Joint Implementation(JI) and the Clean Development Mechanism(CDM). The CDM enables Annex I countries to the Kyoto Protocol to partially meet cost-effectively their emission reduction commitments by undertaking GHG mitigation Projects in developing countries, which do not have any GHG abatement obligations and where the emission reductions are cheaper. One of the major barriers hampering the wide spread implementation of CDM is the high transaction costs associated with the initial identification of promising CDM projects. This paper presents development of a pre-validation program of CDM. The developed program may provide a useful aid to potential investors and project developers as a supportive pre-evaluation tool, and may become an effective tool for the promotion of renewable energy and fuel switching projects.

Spent filters with a high radiation dose rate of 2 mSv·hr^-1 or more are not easily managed. So far, the Korean policy for spent filter disposal is to store them temporarily at nuclear power plants until the waste filters can be easily managed. Nuclear power plant decommissioning in Korea is starting with Kori unit 1. Volume reduction of waste generated during decommissioning can reduce the cost and optimize the space usage at disposal site. Therefore, efficient volume reduction is a very important factor during the decommissioning process. A conceptual method, based on the experiences of developing 200 and 800 ton compactors at Orion EnC, has been developed considering worker exposure with the followings a crusher (upgrade of compaction efficiency), an automatic dose measuring system with a NaI(Tl) detector, a shield box, an inner drum to prepare for easy handling of drums and packaging, a 30 ton compactor, and an automatic robot system. This system achieves a volume reduction ratio of up to 85.7%; hence, the system can reduce the disposal cost and waste volume. It can be applied to other types of wastes that are not easily managed due to high dose rates and remote control operation necessity.

Downsizing IS is rapidly emerging as one of new information systems of the 1990s that involve (1) the cost reduction, (2) the reduction of MIS staff, and (3) the transfer of IS functions to end-users. As downsizing is relatively new information systems, little is known about the causes, the process, or the consequences of downsizing. Case study was chosen as the research methodology of this study. The downsizing IS of Namsun Aluminum Co. was chosen for the exploratory case study. The detailed and qualitative analyses to Namsun were performed with the use of observation, participation, interview techniques. Consequently, the causes, the process, and the consequences of Namsun's downsizing were analyzed. As the main cause, downsizing was started with the purpose of cost reduction. The important consequences of downsizing are as follows ： (1) About 700 mi1lion won reduction in the cost of initially developing the downsizing was achieved. (2) Downsizing is performing Namsun's mission critical applications. (3) Namsun's downsizing could be considered to be SIS(strategic information systems).

Continuous efforts have been made to transform industrial technologies possessed by private sector for national defense purposes over decades. Among these efforts, the unification programs between military and commercial specifications resulted in cost reduction and high efficiency of military supplies. In this paper, we study the unification of reliability specifications, which seems to have been widely used for military and commercial fields. We also propose a method of developing an unified reliability specification for electro-mechanical relays.
