  • According to the Article 4(Confirmity Assessment)of the Electrotechnical Regulation, Confirmity Assessment for the Electrotechnical Regulation decides confirmity of Electrotechnical Regulation; whether to satisfy performances and requirements(determined from Electrotechnical Regulation). It evaluates technical requirements, new technology and standards. However, it does not evaluate technical content stated from Electrotechnical Regulation & Conformity Criteria. From Confirmity Assessment, the technology will be decided whether to fulfill performances and technical requirements. Which is predetermined by contents related to Electrotechnical Regulation. Test standards and test conditions will be overlooked to determine its performances and technical requirements for safety. This paper will show that, studies have been done to determine the guideline for Confirmity Assessment, which is evaluated from performances and technical requirements associated with Confirmity Assessment of electrical installation for new technology of wireless power transfer.

  • Currently in Korea, the lack of facilities and technical criteria for the performance test of small hydropower degrades the efficiency of the domestic small hydropower turbine, and makes it difficult to objectively evaluate the performance of hydro turbine. Therefore Korean institute of water and environment in K-water planned making a basis of performance test of small hydropower by using our flowmeter calibration system the largest one in Korea. We planned the maximum measurable power of hydro turbine will be 200 kW in our system. Improving the efficiency of small hydropower system can achieve the additional development benefit about 1.5 billion won per year.

  • Our Study aims to examine, from a critical perspective, recent approaches to the definition of services, Studies that deal with the question of how to characterize services offer three types of response. The first approach developed by classical economists proposes to use technical criteria (immateriality, non-separability between consumption and production, non-storage, heterogeneity) as foundation for a specific definition of services. The second, which is today most widely cited definition, that of Peter Hill proposes an institutional or a relation-oriented definition which emphasizes service triangle. Finally, the work of Gadrey, which investigates the impact of new technologies on service activities, offers a new general definition of services that is compatible with the existence of several demand rationales.

  • Various forms of procurement are open to companies when constructing new owner-occupied properties. The selection of a form of procurement is an important decision-making problem for companies and their Corporate Real Estate Management (CREM) departments. With this in mind, a decision support tool has been developed to optimise the outcome and success of company's proposed real estate development projects and is presented in this paper. This model can also be used for current real estate portfolios to optimise returns in the long term. In pursuit of this objective and in order to provide an academic basis for this study, decision-relevant goals and parameters were initially identified from the referenced literature used in our research. These were subsequently evaluated in a case study of a corporate development project and identified as specific decision criteria from the perspective of the CREM. The investigation identified 15 criteria that are relevant to the corporate decision-making process in procuring and/or developing property. A model for supporting and resolving decision-making problems of this type was derived from decision theory. In this paper, a decision-making tool is presented that takes into account all the decision criteria from the CREM point of view for the first time. This model should therefore serve as an aid in implementing the decision-making process for the development of real estate projects in a more structured and transparent manner.

  • Every public agency governing infrastructure has to plan effectively for rehabilitation of existing facilities within the constraints of the capital program. Numerous technical, social, political, financial, and management constraints govern the decision to rehabilitate a facility. However, without a systematic procedure for selecting facilities for rehabilitation, within the prevailing constraints, it is possible that the funds available for rehabilitation might be suboptimized. Therefore, a decision support system that assists the user in selecting facilities for rehabilitation while considering the technical, social, financial, and political and management constraints will be useful in the decision-making process. This paper compares the Analytical Hierarchy Process (AHP) with the Swing Weight method used to prioritize functional criteria for suburban station rehabilitation. This paper also contains a brief discussion about the relevance of the Multi Attribute utility theory in developing a decision model for the problem at hand. The results of this paper provides the user with a decision support system that would prioritize the stations in order of their weights obtained by a systematic evaluation of various criteria and sub-criteria involved in the decision making process

  • A selection technique for innovative projects on the beginning stage has been presented in this article. It can be applied in projects assessment in HEI, enterprises, development institutes, etc. It is rather difficult to assess the project quality on the beginning stage of R&D due to the uncertainty in the technical and economic indices but the new development analysis on this stage is of a great interest. By innovative project quality as a management object we will mean those characteristics relating to the results capacity of the projects and its realization process to satisfy the requirements to the innovative products competitiveness and their innovative attractiveness for investors. The most important question in the innovative projects management is the determination of its quality level under modern conditions. The aim of the research is to analyze and evaluate the decision making during the project management process. The objectives and hypotheses are assessment of an innovative project with the application of McKinsey's model is better to realizes by 3 stages: a) selection of optimal criteria; b) determination of weighing coefficients; c) projects positioning in a matrix.

  • 원자력발전소의 데이터 네트워크와 연관된 안전 계통들은 다양한 IT (information technology) 네트워크 및 응용프로그램들을 적용하여 현대화되고 있다. 발전소 데이터 네트워크의 출현과 더불어 원전 계측제어시스템들은 최신의 디지털화된 마이크로프로세서에 근간을 둔 시스템으로 진화하고 있는 반면에, 일반적인 IT 환경에서의 각종 정보시스템이 가지는 사이버보안 취약성 및 사고의 가능성이 증대되는 단점을 가지게 되었다. 이를 보완하기 위해 원전에 적용하는 데이터 네트워크는 신뢰성, 성능 및 보안요건을 충분히 고려해서 설계되어야 한다. 본 논문에서는 원전 계측제어계통에 적용되는 안전한 네트워크의 설계 및 평가 시 사용될 수 있는 기술적인 보안 기준들을 제시하였으며, 본 기준들을 적용하여 설계 및 운영되는 발전소 데이터 네트워크는 외부의 사이버 위협으로부터 효과적인 대처를 할 것으로 판단된다.
