This study is to consider varying factors of jnternal/external informational and operational environments in libraries, and develop a new evaluation indicators for university libraries in digital environments. The main research results are as follows. First, the results through the Delphi method that was to adopted to verify evaluation items and indicators determined by the literature review show that the repressed values for each evaluation category is greater than 3.00, overall average is 4.02, and standard deviation is ranged from 0.40 to 0.62 for each category. This means that the evaluation indicators are valid. Second, the factor analysis was performed to verify .the construct validity of evaluation indicators. As a result, the cumulative variance of evaluation indicators consisting of 11 dimensions per factor is 72.733%. In turn, this result shows that the validity of these indicators is very reliable. Third, t-test and one-way ANOVA are performed within significance probability 0.05 in order to verify differences in each librarians point of views for the degree of importance in evaluation indicators. Based on the Delphi study and our own analysis, we developed a new evaluation indicators that consists of 7 evaluation categories, 35 evaluation items, and 92 evaluation indicators.

Globally, under the leadership of advanced ICT countries, the private sector is promoting various policies to promote the digital transformation of public services. Looking at the research trend, design of public service indicators, development of evaluation system, and empirical research are being carried out steadily, but there are insufficient research cases on models in which the private sector participates in the planning, development, and operation of public services. In this study, Private-centric digital public service suitability evaluation indicators were discovered through interviews with experts in various fields, and weights for each indicator were analyzed through AHP evaluation. In addition, by applying the analysis results to 18 digital public services on a trial basis, the importance and priority of evaluation indicators for each service were derived, and at the same time, the evaluation framework was designed and applied to diagnose implications. As a result of the study, 'social utility', 'corporate acceptability', and 'public acceptability' were selected as the top three indicators of suitability evaluation. At this time, it was analyzed that the weight of the 'company acceptability' index, which includes sub-indices such as 'service profitability', 'service scalability', and 'private initiative possibility', was the highest among the three top indicators. As a result of the demonstration for public services, "IoT facility unmanned remote monitoring service", "blockchain real estate transaction service", and "digital twin disaster prediction service" were evaluated as the most suitable public services for the transition to the private sector.

Recently, an evaluation for information system performance analysis an investment effect quantitatively and qualitatively. So various performance evaluation methods are applied to overcome a limitation which is based on traditional investment returns. However a performance evaluation in public service only derives that a result which is qualitatively evaluated about evaluation domain is yes or no, the performance evaluation does not improve in quality of information system. So in this paper we improve existing performance evaluation methods in public service and add a quality evaluation and quantitative evaluation in the methods. Therefore we propose an integrated evaluation model which guarantees objectivity and reliability of evaluation result and which improves an information system. We consider a project object of an Administration Information DB Construction Project which is promoted in information-oriented project and derive an evaluation result which is applied reflection ratio and weight in each evaluation domain to show a validity of the proposed model.

Since risers have to be operated without being replaced during the design life time after installation, fatigue evaluation as well as strength analysis should be performed. The fatigue life of the riser is known to be dominantly influenced by wave loading and vortex induced vibration (VIV) phenomena. The fatigue life evaluation method and the behavior characteristics of the riser by the wave have been done a lot. Even though the VIV is an important source of fatigue damage for SCR, the evaluation method and behavior characteristics by VIV have not been studied relatively. Most of the S / W for calculating VIV fatigue are a semi-empirical model based on various theoretical models and experiments. For better understanding of VIV response, it is necessary to investigate the effect of parameters which affects the analysis result. This paper summarizes the results of parametric study performed to enhance the understanding of relationship between each parameter and fatigue analysis result.

The purpose of the study was to suggest a cycle wear top jersey improved in mobility. The study developed a new cycle wear with improvement in dissatisfaction factors by planning design, pattern and the functionality of fabric. Considering the amount of sweat and the necessities of compression part, the basic material, the additional compression material, and the mesh material were arranged differently according to areas. The assessment of the developed cycle wear was composed of wearing comfort evaluation by female cyclist, photo analysis and garment pressure evaluation. The developed cycle wear was evaluated and compared with the current cycle wear. As a result of wearing comfort evaluation, the developed cycle wear was evaluated as better than the existing ones in all part, particularly in the areas of reflection tape and materials, partial pressure, pocket size, and prevention of loss. Photo analysis was in agreement with the appearance evaluation of the participants. As a result of garment pressure evaluation, the front neck part was more comfortable and the upper arm, abdomen, and waist area showed higher pressure, so it partially supported the body. This study has significant meaning for developing a new cycle wear top, protecting the body and improving the exercise effect.

In a sensory evaluation, the data obtained by a result of evaluation have a wide dispersion and fuzziness because human sense organ is used as a means of measuring sensation instead of measuring instruments. These dispersion and fuzziness are caused by all kinds of time error and have a great influence on a sensory evaluation, but most of previous papers don't deal with these time errors. In this study, a comparative judgement capacity of an evaluator is discriminated by means of the eigen-structure analysis on the premise that evaluation value of sensory evaluators obtained by a paired-comparison become different by the order of sample presentation

Many cut slopes are located along national roads, there were the collapse of cut slopes. In this study, the weights for condition evaluation of rock slopes was calculated using the entropy method and analytic hierachy process(AHP) method. The entropy analysis was performed using 95 cut slope data, and the AHP analysis was performed by a questionnaire to several expert. The weights based on analysis results were compared with evaluation weights of existing standard. As a result of this study, there was the difference of weights among the analytical methods. Later on, if this study's results is used to improvement current evaluation weights, it will be possible to perform the reliable condition evaluation.

This paper evaluates thequality of synthesized speech by rule using the LPC CD in the objective measure and then compares the result with the subjective analysis. By evaluating the quality of synthesized speech by rule objectively. We have tried to resolve the problems (Evaluation time or size expansion, variables within the analysis results) that arise when the evaluation is done subjectively. Also by comparing intelligibility-the index for the subjective quality evaluation of synthesized speech by rule-with evaluation results obtained using MOS and the objective evaluation. We have proved the validity of the objective analysis and thus provides a guide that would be useful when R&D and marketing of synthesis by rule method is done.

This study aims to suggest the detailed evaluation criteria based on performances for rock slopes. Using the previous research result, final evaluation items are proposed considering characteristics and similarities of each evaluation item. Weight for each evaluation item is deducted using AHP method, verification for suggested evaluation criteria is conducted based on correlation analysis. The research results as follows. All evaluation items have a high statistical correlation with final evaluation result(safety rating). Especially, items of the "rockfall", "ground deformation", "discontinuity characteristic", "instable lithology" were shown the highest in relative correlation coefficient(R), It is judged that items and weight presented in this study well reflect characteristics of rock slopes.
