Human experts have the various own knowledges to be applied in specialized domains. The fact that knowledge itself becomes more critical in the context of textile knowledge with rapid development of new fibers, automated equipments, processes and applications. Diversity of worsted spun yarns, lack of human expertise, and inconsistency among manually generated process plans in consequency of adjustment machine parameters owing to change up raw materials frequently increase the necessity of developing computer aided process planning(CAPP) systems for spinning process. Expert systems offer one of techniques to develop CAPP systems which would behave in a knowledgeable manner. Expert systems are the problem-solving computer program that can reach a level of performance comparable to that of a human expert in some specialized problem domain. This paper is described as job justification module. The job justification module performs to consult with users on which worsted spun yarn manufacturing process planning under the various factors, e.g., raw materials, machine parameters and required yarn counts. Also, the developed module informs the various knowledges relevant process planning. The job justification module offers the control parameters at each process and includes the various standard process plans as database. These knowledges are generated by facts and rules within rule bases.

본 논문은 신교통 시스템인 경량전철을 도입하기 위한 기본계획 추진과정에 진행하여 온 국민참여(Public Involvement) 활동 사례를 대상으로 정보공유 이전과 이후의 신교통(LRT) 기본계획(Master Plan)에 대한 수용의식의 변화를 구조방정식모형(SEM)을 이용하여 분석하였다. 그 결과, 시민들은 설문조사, 홍보자료 제공, 오픈하우스 및 공청회(Public Hearing) 개최 등과 같은 PI 활동이 신교통(LRT)기본계획에 대한 중도적 의사표현에서 확실한 의사 표명으로 변화시키는 효과가 있었다. 이상 분석결과 철도사업의 PI는 해당 사업의 수용의식에 부정적 혹은 긍정적인 영향이 모두 존재할 수 있기 때문에 합의 형성이라는 결과물보다는 국민들에게 의사결정 할 수 있는 정보제공의 기회와 함께 철도사업의 절차적 정당성을 향상시킬 수 있도록 제도화가 필요하다.

Major problems involved in an electrical utility expansion planning within a time horizon are how to efficiently deal with objectives considering multiple factors and uncertainty. But justification factors in study these days have considered only quantitative factors except qualitative factors. Therefore, the purpose of this paper is to develop a new model for economic evaluation of nuclear power plants through the scoring model with the quantitative and qualitative factors under uncertainty. The quantitative factors use a levelized generation cost method considering time value of money. Especially, the environmental, risk, and safety factors in this paper have been also explained for the rational economic justification of the qualitative factors under uncertainty. This paper not only proposes a new approach method using the scoring model in evaluating economy of the nuclear power plant in the long term, but also provides the more efficient decision making criterion for nuclear power plants under uncertainty.

Strategic information systems planning (SISP) remains a critical issue of many organizations and also the top IS concern of chief executives. Therefore, researchers have investigated SISP practices and tried to improve a methodology. Among the various issues of SISP, systematically determining subject database groupings and fully automating the processes are important aspects. This study presents an alternate methodology using a statistical technique, a variable clustering approach, and systematic rules for determining database groupings, which can be fully automated. This methodology provides a strong theoritical justification as well as systematic and simple criteria for database groupings, enhanced interpretability of the output, and would be easy to include in CASE software application.

The objective of this paper is to investigate the development of Silhak as a Korean epistemology, to investigate the implications of Silhak in Korean society, and to discover further environmental implications. The main discussion of this paper concerns with the epistemology of environmental philosophy. Epistemology is based on the justification of certain knowledge and social philosophy. Epistemology, from the Greek words episteme (knowledge) and logos (word/ speech) is the branch of philosophy concerned with theories of the sources, nature, and limits of knowledge. Since the seventeenth century, epistemology has been one of the fundamental themes of philosophers, who were necessarily obliged to coordinate the theory of knowledge with the development of scientific thought. It is a general belief that Western ideology is substantially embedded in Eastern ideology due to physical and metaphysical colonial involvement. We argue that ecological crisis may be resulted from western epistemological mechanical view, thus we suggests a Korean epistemology as an alternative. In this paper, we seek possibility of epistemological alternative of nature in the Korean traditional epistemology incorporating the epistemology of Sung confucianism and The Silhak.

The purpose of this study is to dimensionally examine the factors of policy changes by applying the ACMS model to KEPCO's structural reorganization privatization policies and study its implications. As a result of the analysis, among the external variables that affect as a financial source or restriction to advocates, all areas except for the difference in opinion of the people as well as policy decision and effects of other subordinate systems were shown to be in an advantageous condition acting as a financial source to advocates of structural reorganization privatization. On the other hand, advocates affected by the external variables share a certain belief system in which the advocates of privatization share the justification of profitability while the advocates of collectivization share the justification of publicness. In these flows, the announcement of the privatization plan of public enterprises of the committee of planning and budgeting acts as a matter of contact which opens the windows for policy changes, and this window goes through ignition, explosion, and fixation which causes fierce interactions among advocates of both sides. Eventually, in accordance with the contents of excluding electricity(KEPCO) from the list for privatization the window for policy changes has closed and things have changed to a transitional KEPCO privatization policy. Based on this, the first implication is that non-official participants such as the people, social organizations, labor unions, etc. influence policy changes more than they did before. Secondly, in the process of policy changes, there is an order of boundary even in the fierce interactions between each advocate. Thirdly, specific variables can play various roles in complex policy phenomenon. Fourthly, a logical analysis using the ACMS model is possible in Korea as well. Fifthly, as a result of analyzing the change process of the KEPCO structural reorganization privatization policy through the ACMS model, not all matched with the main research results implied by the ACMS model.

The discussion of this paper is concerned with the epistemology of urbanism and rurality, that is, the justification of certain knowledge claims about how to intervene in understanding of urban and rural way of life and their implications to space. It is not concerned with the search for "truth" as such, but rather with the construction and presentation of knowledge as truth that subsequently lead to interpretation in the form of scholarly arguments. Rural areas vary considerably, and we define it as of a socially constructed category and so does urban as a comparative construction. As with community, rurality has been defined in widely different ways so has urbanism. In identifying and interconnecting these two concepts, we incorporate diverse western epistemologies such as empiricism and pragmatism. In addition, we heed particular attention to the intellectual history of Silhak, a philosophical ideology of Korea, to identify the relationships and it's effect on social way of life encompassing the realm of rural and urban spaces. We found that Silhak is particularly useful in that it deals with substantive issues of the relationship between rurality and urbanism arising from the discordance between values and perceive conditions of the rural and urban way of lives. This paper argues that the epistemology of Silhak is particularly superior to those of western ideologies since it accentuates unity of spaces rather than differentiating urban and rural way of life. We concludes with demanding more studies in the field of urban and rural analyses incorporating more diverse concepts of Korean orthodox epistemology.

At both international and national levels, such as in the Rio Declaration and the EU's Fifth Environmental Action Plan, governments have committed themselves to the adoption of the precautionary principle (UNCED 1992, CEC 1992). These commitments mean that the existence of uncertainty in appraising policies and proposals for development should be acknowledged. Uncertainty arise in both the prediction of impacts and in the evaluation of their significance, particularly of those cumulative impacts which are individually insignificant but cumulatively damaging. The EC network of EIA experts, stated at their last meeting in Athens that indirect effects and the treatment of uncertainty are one of the main deficiencies of current EIA practice. Uncertainties in decision-making arise where choices have been made in the development of the policy or proposal, such as the selection of options, the justification for that choice, and the selection of different indicators to comply with different regulatory regimes. It is also likely that a weighting system for evaluating significance will have been used which may be implicit rather than explicit. Those involved in decision-making may employ different tolerances of uncertainty than members of the public, for instance over the consideration of the worst-case scenario. Possible methods for dealing with these uncertainties include scenarios, sensitivity analysis, showing points of view, decision analysis, postponing decisions and graphical methods. An understanding of the development of cumulative environmental impacts affords not only ecologic but also socio-economic investigations. Since cumulative impacts originate mainly in centres of urban or industrial development, in particular an analysis of future growth effects that might possibly be induced by certain development impacts. Not least it is seen as an matter of sustainability to connect this issue with ecological research. The serious attempt to reduce the area of uncertainty in environmental planning is a challenge and an important step towards reliable planning and sustainable development.

Container terminals at Gwangyang Port are operated by three container operators: A, B and C. Ultimately, there is consensus that a single operator should operate all terminals so that economies of scale can be achieved even in the operation of the container terminal. Integration between operators has a positive effect on both operators and shipping companies. From the operator's point of view, overlapping fixed costs between operators can be unified, reducing overall costs and utilizing spare facilities. On the other hand, from the viewpoint of the shipping company, it is possible to ensure stable use of the port facilities and always allow berthing, reduce days on demurrage and ship waiting, and provide one-stop service for work. However, existing cases of operators' integration or relocation of terminals remained to estimate the expected effects of alternatives, emphasizing only the financial point of view. The port terminal is a large system, and it is important to consider that it is an aggregate of major logistics facilities and equipment. Moreover, if the estimation can be made by quantifying the expected effect, the justification of the terminals' relocation can be further emphasized. Therefore, it is very important to estimate the expected effect from the viewpoint of systemic operation. Moreover, the need for operators' integration can be further emphasized if it can be estimated through quantification of expected effects. Currently, three alternatives are considered as alternatives to the terminals' relocation, and in this study, the optimal plan was derived for the 3 alternatives by the linear planning model of the minimum shuttle transportation cost in the terminal. The optimal plan is alternative 2, which shows the most advantageous integration effect in terms of expected effects. Alternative 2 integrates the B terminal into the C terminal, and the A terminal operates independently as it is.
