In the consumer products industry, it has been highly desirable to develop objective test methods to replace subjective evaluation methods. In developing an objective test method, subjective evaluation data should be on a linear scale. According to Thurstone's theory of comparative judgment, a%-preference from a paired-comparison test can be converted to a linear-scale value. The required number (N) of paired-comparison tests increases dramatically as the number of products increases. This problem should be solved by classifying the total products into several subgroups consisting of 3-4 products in each group. By doing so, it can not only significantly reduce the number of required paired-comparison tests, but it can also obtain more reliable, reproducible data.

The use of technical proposal tendering has been expanding recently with the aim of effecting cost reduction, quality enhancement, technological development and value realization centered on multifunctional administrative cities, innovation cities, and the Yongsan relocation project. In line with the increasing interest towards life cycle cost improvement measures as an important evaluation category concerning technical proposal tendering, efforts in preparing measures that can execute the security of credibility and objective evaluation concerning architectural life cycle cost are being made. However, problems such as lack of applicable cases of design development and detail design, distortion of initial construction costs concerning the original plan, combination of constant price and current price, the ambiguity of the calculation standards between tendering corporations, inaccuracy of terms, and insufficient compositional formats concerning life cycle improvement measures are being cited. Accordingly, this study sought to propose a measure to improve the compositional guidelines, format, and standards so that a systematic life cycle cost evaluation can be executed for the reliable distinction of each participating corporation, enhanced credibility and objective evaluation of the life cycle cost improvement measure for technical proposals.

Bidding systems in the domestic public construction work have been amended many times since the lowest-bidding system was implemented in 1951. However, this hasn't had much success. Competition in technical development among companies has declined as the contracts for buildings are given to company which submits the lowest price without considering traits of projects. In addition, as the construction market turns to the limitless competition system due to FTA(Free Trade Agreement), advanced techniques are needed to promote the national competitive power. Considering the needs of the times, Korean government announced that "Best Value Contract (Design-Bid-Build)" and "Bridging Contracts (Design-Build)" are included to 4 existing bidding systems in October 2007. Thus this study aims to suggest devised the evaluation criteria including major items for evaluating bidders, in order to establish and revitalize the best-value bid system successfully.

Exposure to gamma-rays is hazardous for humans and other living beings because of their high penetration through the materials. For this reason, shielding materials (usually lead, copper and stainless steel) are used to protect against gamma rays. This study's objective was to prepare ceramic materials for gamma radiation shielding by using different natural bentonite clays. Gamma-ray attenuation performances of the prepared shielding materials at different thicknesses were investigated and evaluated for different gamma-ray energies from different standard point gamma radiation sources (²⁵¹Am, ⁵⁷Co, ¹³⁷Cs, ⁶⁰Co, and ⁸⁸Y). The mass and linear attenuation coefficients of the prepared ceramics vary between 0.238 and 0.443 cm² g^-1 and between 0.479 and 1.06 cm^-1, respectively, depending on their thicknesses. Results showed that these materials could be prioritized because of their evidential properties of gamma radiation protection in radiation applications.

We have developed three evaluation checklists of educational softwares for users such as, learners, teachers and parents, not for the software develops or designers. This study has especially focused on CD-ROM titles and softwares on the internet. The followings were selected as the essential attributes that the educational softwares of high quality should possess : ease of use, technical support and interest of learning for learners, educational value and smartness for teachers, packaging integrity, investment value and childproof for parents. The evaluation checklists were developed on the basis of evaluation criteria which were concretion of the essential attributes. The validity of the evaluation checklists was supported by a theoretical study for the development of ckecklists and the actual development process. The interrater reliability and the retest reliability were confirmed by statistical methods. Thus, the developed checklists can be a useful tool to evaluate educational softwares. This study will contribute to improvement of the software quality and help users in selecting educational softwares.
