  • The quality characteristics of bread prepared with the addition of dried persimmon peel powder(PPP) were investigated. Visco-elastic characteristics of dough and texture of bread added PPP was examined by rapid visco-analyzer and texture analyzer. The maximum viscosity of the dough with PPP was lower than that of control at 90\^C. Final viscosity after cooling to 50\^C, viscosity of control increased to 134 B.U., but that of the dough with PPP showed 13∼37 B.U. As more PPP was added, gluten formation and mixing time dough were longer. Adhesiveness, springness, cohesiveness and chewiness gradually increased as PPP content increased, while the hardness decreased. Lightness value decreased but redness and yellowness values increased with the addition of PPP, especially, the bread made by 15% PPP treatment showed dark brown color. In sensory evaluation of bread, score of color decreased significantly as more PPP was added but overall acceptability was not significant different(p<0.05) between control and 5% PPP treatment. It is considered that the addition of 5% was appropriate for bread making with PPP.

  • The purpose of this study is to present the rational decision process for new ward office building site. AHP Technique used in this study considers both quantitative and qualitative factors on the basis of decision maker's intuitive, reasonable or unreasonable judgement by giving weight through mutual comparision of publicity factors. The evaluaion factors were refer to another five ward office there were executed these kinds of new site selection before. These standards are composed of 6 middle groups and classified into 9 detailed standards. Alternative building sites are five places in this district. The final evauation standards are Accessibility, Urban Expansion Possibility. Distrct balance, Environment, Financing. Development easiness. And It became clear that the priority of evaluation is Financing > Urban expansion > Accessibility > Development easiness > District balance > Environment. In conclusion, it was determined that alternative " E " is the most adequate place for new ward office building.

  • This study was aimed at evaluation of residual stress of steel pipe structures. The production process of pipes was complex (at first bending was done by roll forming or press forming and welding was final process of making of steel pipes). So there could be effected high residual stresses in steel pipes. In order to evaluate the changes of residual stress the locations of measurement were selected carefully. Measurements of residual stress were done for various kinds of pipes (shapes in circular and square). For the evaluation of residual stress, hole-drilling method (ASTM E837 was applied. The results showed that along the weld Eine high tensile stress were measured as effected, and high tensile stresses were measured where large plastic deformation developed. Through these efforts, experimental results could be more effectively assisted by numerical method.

  • The purpose of this paper is to publish IITA's R&D planning and selection procedures for review by outside panels and by industry. The paper illustrates the detailed procedure and criteria used at each phase of evaluation process to the results of National Survey for Information and Telecommunication Technology Needs. Total 293 project ideas come from industry, government-supported research institutes, and universities. Candidate projects are not evaluated on the basis of what technology is proposed, but on how sound the proposed idea is within that technology and on the potential economic impact. In addition, an industrial assessment of the project ideas was performed as part of an evaluation process. At a final stage, 90 projects are selected.

  • The Analytic Hierarchy Process (AHP) is known as a very useful decision-making model developed for obtaining the relative weights of alternatives through pairwise comparison in the context of hierarchical structure. In this paper, we propose a method to reflect the reliability of evaluators in the process of pairwise comparison. This method is applied to the evaluation of aerospace technology alternatives. We have conducted a questionnaire survey for S company that is one of the representative aerospace companies in Korea. A questionnaire was designed for obtaining both the priority with considering the reliability of evaluators' importance weights (the modified AHP priority) and the priority with assuming equally reliable evaluators' importance weights (the AHP priority) in order to compare the priority derived by each of two methods. The result shows that there exists the difference hard to neglect between the final priorities gained by two methods.

  • For a rational evaluation of the spatial distribution of consolidation settlement, it is necessary to adopt probabilistic method. In this study, mean and standard deviation of consolidation settlement of whole analysis region are evaluated by using the spatial distribution of consolidation layer which is estimated from kriging and statistics of soil properties. Using these results and probabilistic method, the area need to be raised the ground level for balancing the final design ground level are determined.

  • Since the columns with flexure-shear failure have lower ductility than those with flexural failure, shear capacity curve models shall be applied as well as flexural capacity curve in order to determine ultimate displacement for seismic design or performance evaluation. In this paper, a proposed modified shear capacity curve model is compared with the other models such as the CALTRANS model, Aschheim et al.'s model, and Priestley et al.'s model. Four shear capacity curve models are applied to the 4 full scale and 7 small scale circular bridge column test results and the accuracy of each model is discussed. It may not be fully adequate to drive a final decision from the application to the limited number of test results, however the proposed model provides the better prediction of failure mode and ultimate displacement than the other models for the selected column test results.

  • Efficient development of method on a performance evaluation for machine tools has been regarded as the most important work for accuracy and quality enhancement to every user and manufacturer. A evaluation method of accuracy for machine tools has been studied recently according to the rapid increase of interest in precision machine tools. To this point of view, the circular interpolation test of machine tools is recognized as the most useful method to distinguish a dynamic accuracy of NC machine tools by ISO and ANSI/ASME, etc. In this paper, we have studied and developed the form measurement system with grid encoder to analyse the final accuracy of NC machine tools. we have analyzed the servo system error and geometric error of NC machine tools through measuring a dynamic error signal by this system. and then we verified the experimental result and enhanced the reliability by means of comparing the characteristics of the developed system with the kinematic ball-bar system.

  • The aim of this study was to develop a portable electronic nose system for freshness measurement of meats, which could be an alterative of subjective measurements of human nose and time-consuming measurements of conventional gas chromatograph methods. The portable electronic system was o optimized by comparing the measurement sensitivity and hardware efficiency, such as power consumption and dimension reduction throughout two stages of the prototypes. The electronic nose systems were constructed using an array of four different metal oxide semiconductor sensors. Two different configurations of sensor array with dimension were designed and compared the performance respectively. The final prototype of the system showed much improved performance on saving power consumption and dimension reduction without decrease of measurement sensitivity of pork freshness. The results show the potential of constructing a portable electronic system for the measurement of meat quality with high sensitivity and energy efficiency.
