  • Korea Water Resources Corporation (KOWACO) annually supplies about 2 billion Kwh and 7.3 billion $m^3$ with its 10 multi purpose dams and 20 water supply offices. For the proper control and management of the above utilities, sequential control equipment and SCADA/DCS have been operated and maintained. In this paper, 8 control system evaluations for hydropower dam, water supply, electric power and subway projects during 1984-1997 were reviewed and analyzed. The systematic evaluation method has been established in the points of the purpose, method, procedure, evaluation team, evaluation criteria, total evaluation table and the contents of final recommendation report. With keeping in mind the essential points, it is expected for the more effective and fair evaluation of bids.

  • This study introduces an environmental noise evaluation procedure and results for a wind turbine (W/T) system. Test and evaluation are required by the international standard IEC 61400-11 in the aspect of environmental effect. Test and evaluation are performed on U-50 WT model which is first developed by the domestic W/T manufacturer. W/T test model is under operation in Daekwanryung wind test site. An integrated monitoring system in the test site is utilized for the evaluation. With the noise signal, meteorological data and W/T operational data are monitored in real time by the integrated monitoring system using LabVIEW. From the measured noise data, acoustic power level are estimated and compared with those of other similar size WT under the wind speeds required by international standard.

  • By deriving the limitations of the test evaluation, it was intended to suggest a plan to improve the test evaluation system for the appropriateness of the number of ship crews according to the design and construction of troops-saving ships. Currently, the number of crew members by ship type is confirmed and specified in the ROC(Operation Requirement Performance) in the early stages of design, such as conceptual design, but there is a limit to testing and evaluating the appropriateness of ensuring reliability of combat performance.

  • The jury instruction consists of a set of legal rules and provides a guide for jurors to interpret evidence and the legal standard of a proof beyond reasonable doubt. Jury instructions are usually given after the closing arguments (at the end of the trial). But some research has shown that jury instruction provided before the evidence may have an impact on verdict. The present study was to determine the cognitive process caused by early instruction: (1) Early instruction may influence the verdict by upwardly adjusting the threshold for the decision to convict; (2) early instruction may influence the verdict through evaluations of the probative values of evidence; (3) Or both. 187 people older than 20 years of age participated in the on-line survey. With a trial scenario, one independent variable, Instruction Procedure, was manipulated in three levels: before-and-after the evidence procedure, after-only evidence procedure, and no-instruction procedure. The instruction procedure conditions did not show any difference in the evaluation of the probative values of evidence. On the other hand, before-and-after condition showed the lowest rate of guilty verdict and the highest probability of guilt for the defendant in the scenario. This latter result clearly suggested that the instruction procedure affects the decision threshold. Specifically, instruction provided twice, once before and again after the evidence, may upwardly shift the threshold for the decision to convict.

  • Silica fume influences concrete diffusivity and permeability as well as strength by densifying the microstructure of the interfacial transition zone (ITZ) of high strength concrete, by reducing the capillary porosity of cement paste and by producing less diffusible and permeable pozzolanic CSH gel than CSH gel of conventional cement hydration. This paper presents a procedure to predict the chloride ion diffusivity and water permeability of the high strength concrete containing silica fume. Water binder ratio, silica fume addition, degree of hydration and volume fraction of aggregates are considered as the major factors influencing concrete diffusivity and permeability in the procedure. Analytical results using the procedure are shown and verified with other data.

  • Some aspects of the design procedures of reinforced concrete slabs concerning microvibration behavior have to be considered. In this study, a numerical algorithm for the analysis of slabs to withstand the microvibration effects is developed. First, the evaluation criteria for controlling the microvibration of slabs is given from the literature survey. Second, the human-induced load model is developed by the experimental results. Finally, the procedure for the analysis of reinforced concrete slabs, with particular emphasis to the slab subject to human-induced dynamic load, is developed by the finite element method and is then examined by using the slab model tests, In addition, the effects of elastic modulus, mass, shape of slab, and support conditions on the microvibration behavior of reinforced concrete slabs are analyzed. It is concluded that the developed analysis procedure showns in accecptable accuracy compared with the experiments and the analysis procedure cab be easily appkied to the practical microvibration problems.

  • Instead of testing split air conditioners, an empirically based calculation procedure may be used to estimate the Energy Efficiency Ratio at ARI A test conditions. Typically, the system involving the indoor unit well sold and the given outdoor unit is called the matched system. All other systems involving a given outdoor unit and other indoor units are called the mixed systems. To estimate the EER(A) for the mixed systems, EER(A) for the matched system must be known, Generally, the EER(A) for the matched system is known. This procedure relies on independent measurements and calculations made on an outdoor unit in conjunction with a matched indoor and a mixed indoor coil. A heat pump simulation model was used to quantify the effects of individual system components on the system performance. The procedure is applicable to all air-conditioning units having rated cooling capacities less than 19,000W and charged with refrigerant 22.

  • The physicochemical and sensory characteristics of brown rice flakes by different processing conditions such as flaking Process and their heat treatments were investigated to establish the brown rice flake processing procedure. To successfully make the compressed rice grain type flakes, the most appropriate water steeping conditions were 5 hours at 60'C. The brown rice flakes by compressed flaking procedure and heat treatment with microwave toasting showed the best crispiness-texture that tested from textrometer or sensory evaluation, and there was no significant difference between the source of rice varieties. The water absorption index(WAI) of tested flakes were negatively correlated with the water soluble index( WSI) and positively correlated with bowl life. The flakes made by compressed flaking procedure and heat treatment with microwave toasting showed longer bowl life, which is the length of the time that the cereal can retain its crispness after being soaked in milk.
