Meta-evaluation for national R&D programs should be established within the framework of whole R&D system linked with science and technology needs and objectives. The R&D program evaluation system can be understood as a circulation of input, implementation, output, and utilization. In the result of the Delphi survey, which consisted of twenty-four experts (performed in three rounds), twenty-four indices were developed. The meta-evaluation model included sub-items which were important points of view of it as follow (eight items): propriety of planning, sufficiency of information, and propriety of evaluators in evaluation input; appropriateness of method and appropriateness of procedure in evaluation implementation; credibility of output in evaluation output; and usefulness of report and application of evaluation utilization. As the application of the meta-evaluation model, the total mean was lower than 3.0 of the median value of 2.73 (5 point Likert scale). Finally, it was suggested that the feedback of evaluation results should be more enforced to R&D program improvement particularly (evaluation utilization 2.50).

The purpose of this research is to develop a model for efficient service R&D investment in government budgeting process. It is necessary to develop an efficient and effective investment model to improve competitiveness of the service industry and national economy. Various existing types of service R&D classification have been reviewed. And object-oriented service R&D request classification types have been derived. A tentative model for evaluating service R&D requests have been developed through extensive discussions on effective methodologies. The model has been refined and revised by four service budgeting experts. The revised and refined checklists and guidelines have been used for 40 real service R&D requests evaluations. As a result, a full model for service R&D evaluation and budgeting has been proved to be useful. Also, a need for more efficient and concise evaluation model has been raised through this evaluation process. A brief model with only 10 checklists has been developed and its usefulness has been proven by pilot test with 10 real service R&D requests. The results of this study can be used for evaluation of service R&D proposals and effective budgeting of R&D requests for improving global competitiveness. Further research is needed for refining the developed evaluation models.

This study aims to enhance the usability of eBook reader programs on personal computers through heuristic evaluation in order to learn users' perceptions and derive key elements for interface design. For this purpose, the traditional usability evaluation and heuristic evaluation method were studied. A total of 22 evaluators of the heuristic evaluation were taken by purposive sampling to test the interface of eBook reader on PCs. This study suggested ten heuristics that focus on improving and specializing the usability aspects of reading digital materials.

In this paper, we propose a novel method to analyze and quantitatively evaluate the impression of landscapes and soundscapes about traditional area of Chungnam Asan city in Korea. For this, we collated data about impression evaluation of Korean and Japanese students and, based on these result, we proved the validity and usefulness of the evaluation system that we proposed through this study. The research process conducted in this study as follows: first of all, we had selected five traditional places of interest in Asan City, and investigated various conditional elements of the area including soundscapes which is forming the landscape using video camera. And we made both Korean and Japanese students evaluate the impression for these videotaped landscape data through using the SD(semantic differential) method. And then, we quantified these qualitative data through applying the quantification theory and cluster analysis method to them. Though this process, we could obtain both data as a result derived by classifying each sample and categorizing levels of those impression evaluation. Because of totally difference between those two analyzing processes, which one is for sample classification and the other is for determining impression level, we could validate the usefulness of our evaluation system through conducting comparative analysis of results from both methods. Analysis showed that our novel evaluation system for landscape is effective and, in most part of the traditional landscape, Japanese students' responses are different far from the Korean students' responses.

The objective of this study is to evaluate the reliability of DEA for the measurement of efficiency of Commercial banks in Korea using the DEA methods. DEA is basically a mathematical programing technique initially developed by Chanes, Cooper and Rhodes(197n) to evaluate the relative efficiency of not-for-profit organizations where multiple outputs are produced with multiple inputs. This study show that DEA approach is not only usefulness in evaluating performance of banks but also a useful bank management tool.

AC AT feeding method consists return circuits of electric train inserting in parallel between trolly line and feeding line and connecting neutral line to rail and FPW. Due to increasing electric load at feeding system, collecting voltage of train and end voltage are going down. So to increase voltage between trolly line and rail, the usefulness of new autotransformer are considered which variation of short impedance and change of line voltage is simulated with modified winding ratio of autotransformer from 1:1 to variable tab.

Formal manipulations of double series are useful in getting some other identities from given ones and evaluating certain summations, involving double series. The main object of this note is to summarize rather useful double series manipulations scattered in the literature and give their generalized formulas, for convenience and easier reference in their future use. An application of such manipulations to an evaluation for Euler sums (in itself, interesting), among other things, will also be presented to show usefulness of such manipulative techniques.

In this study, the usefulness of Radar method by means of assessing deck data-layer properties-was tested on the highway bridge. The obtained GPR data were compared with values measured from drilled cores and damage mapping by the visual survey. It is shown that GPR can provide the highly accurate measurements of layer properties of concrete decks and can map areas of deterioration in bridge by dielectric constants.
