In the knowledge-based economy, technology valuation of patents, brand name, know-how is presented for as key subject of intangible assets management science. This paper reviews the methods of technology valuation that have been developed by valuation specialists. Also, is talking about the practical application by income approach (DCF) method. The function and role of technology valuation analysts such as the related organizations and the reference of foreign organization is appeared through the examples.

Successful implementation of statistical process control techniques requires for operational definitions and precise measurements. Nevertheless, very often analysts can dispose of process data available only by linguistic terms, that would be a waste to neglect just because of their intrinsic vagueness. Thus a hybrid approach, which integrates fuzzy set theory and common statistical tools, sounds useful in order to improve effectiveness of statistical process control in such a case. In this work, a fuzzy approach is adopted to manage linguistic information, and the use of a Chi-squared control chart is proposed to monitor process performance.

Along with the international technology transfer market, as the domestic market grows, more professional technology analysts are needed and it became more necessary to investigate the qualification of those experts to cope with growing market. In this study, the current working condition of those experts is described, qualification system is analyzed and more realistic suggestions on the system to activate the market and to encourage the experts will be introduced. The study was performed based on the questionnaire sent to the person who works in related fields, such as industry, technology transfer center, universities, etc.

대부분의 정보검색 과정들은 웹 페이지의 분석에 따라 검색 로봇을 이용한 검색기법, 카테고리를 이용한 색인 DB를 검색기법, 메타 태그를 이용한 검색기법을 사용하고 있다. 그러나 이러한 기법을 통하여 원하는 정보를 얻을 경우 정확도가 떨어지는 정보가 검색되어 사용자는 다시 한번 검색된 목록들을 확인해야 하는 경우가 발생한다. 본 논문은 다양한 형태의 웹 페이지에 대하여 바이오 인포메틱스 기술을 적용하여 분석, 사용자에게 필요로 하는 정보를 보다 정확하게 제공하는 기법을 제안한다.

Support vector machines(SVMs) are known as flexible and efficient classifier of multivariate observations, producing a hyperplane or hyperdimensional curved surface in multidimensional feature space that best separates training samples by known groups. As various methodological extensions are made for SVM classifiers in recent years, it becomes more difficult to understand the constructed model intuitively. The aim of this paper is to visualize various SVM classifications tuned by several parameters in reduced dimensions, so that data analysts secure the tangible image of the products that the machine made.

The two common numerical methods to approximate the solution of partial differential equations are the finite element method and the finite difference method. They both lead to solving large sparse linear systems. For many applications, it is not unusal that the order of matrix is greater than 10, 000. For this kind of problem, a direct method such as Gaussian elimination can not be used because of the prohibitive cost. To this end, many iterative methods with modest cost have been studied and proposed by numerical analysts.(omitted)

Data envelopment analysis (DEA) estimators have been widely used in productivity analysis. The asymptotic distribution of DEA estimator derived by Kneip et al. (2003) is too complicated and abstract for analysts to use in practice, though it should be appreciated in its own right. This paper provides another way to express the limit distribution of the DEA estimator in a tractable way.

With the increasing complexity of man-made systems, computer simulation has become a widely used tool for the design and analysis of complex system. When computer simulation is used for the purpose of system design, the analysts want to develop strategies to achieve some pre-defined target condition for an output of interest while simultaneously minimizing its variance. The goal of this research is to develop and demonstrate a new method for the design of robust systems with multiple responses using the fuzzy satisfaction function and computer simulation experiments.

The present paper deals with the optimum design of reinforced concrete cylindrical shell tanks in according to ACI 318-89 code. The purpose of this investigation is to find the optimum values of the steel ratio and the effective thickness of reinforced concrete cylindrical shell tanks. The analysts is carried out using a simple computer programming, SMAP(segmented matrix analysis package). The optimization is carried out using GINO programming. Optimum results for cylindrical shell tanks with uniform, stepwise and piecewise linealy varying thicknesses are presented.
