The introduction of KTX (Korea Train eXpress) provided passengers with a much faster mode of transport, and KTX has become a model railway system. Express railway stations are emphasized as public transit transfer centers, but their service evaluations were not performed appropriately so far. It is possible to know the level of service by developing valuation criteria for their evaluations. The evaluation of transfer centers mainly consists of two parts; connective service with other travel m odes, and transfer service inside transfer stations. Connection is defined as the inter-connection of multi-transportation vehicles, and transfer means that a passenger changes his travel mode to another. Such connective service and transfer service are evaluated by the level of service in terms of transfer facilities, the appropriateness of station layout and the quality of information throughout the facilities. We developed the service evaluation indicators of connective facilities and referred to the indicators of transfer facilities. We examined the 7 stations in Korea that are currently in operation and standardized the methodology of the evaluation process by applying the indicators suggested in this study.

Recently International Water Association(IWA) has proposed new performance indicators for water supply services and their successful applications are being reported continually. According to the various reports, the percentage indicators were suggested not to be used for performance comparison, especially where the targeted areas have great difference in consumption per service connection. But unfortunately in Korea the revenue water ratio, one of the percentage indicators is still being used to set up the goal of water-related administration and to compare the performances between systems. Therefore this study aimed to prove the inapplicability of the percentage indicators with nation-wide data and to suggest better performance indicators for more efficient water loss management. According to the result of the comparison of various performance indicators with conventional one, it is roved that percentage indicators ca not evaluate the performance efficiently where the local situations are significantly different. It is suggested that the better performance indicators such as real losses per service connection or ILI should be used to benchmark the performances of water suppliers on water loss management so thai the problems of water losses could be identified easily and recovered effectively.

Objectives : The objective is that we measure and analyze Pulse-Respiration Ratio and Body Composition Analysis to study the correlation between both. Methods : First, after subjects take a rest over 10 minutes, we measure their electrocardiogram and respiration pattern through which we take average peak interval to calculate an average pulse cycle and a respiration cycle. An average respiration cycle divided by an average Pulse Rate gives Pulse-Respiration Ratio. Next, we draw out 22 Body Composition Analysis indicators by using In-Body 720 model. Last, we analyze and take statistics on them by using SPSS 13.0 program. Results : Negative is the correlation between P/R Ratio and Body Composition Analysis indicator like fatness degree, body fat volume, body fat rate, abdominal fatness, BMI. Conclusions : 1. The higher P/R Ratio the more likely to be thin, the lower P/R Ratio the more likely to be fat. 2. We separately analyze P/R Ratio depending on each breathing frequency and pulse frequency to find out that breathing frequency has great influence and that breathing frequency decides the fatness degree. 3. In study on the correlation between P/R Ratio and Body Composition Analysis, fatness degree, in-body fat volume, in-body fat rate, BMI are the related indicators, which shows the connection with the fatness indicators. 4. In study on the correlation between Han-Yeol [寒熱] grade and Body Composition Analysis indicators, the result is that Han[寒] has no connection and that only Yeol[熱] grade has something to do with it, which means the higher heat symptom subjects have, the more basic metabolism volume and muscular build they have.

The true space is the physical world affected a gravity but the cyber space is the world that rise above physical status and show developed space. This study shows that the factors of objective valuation and the indicators for the behavior analysis. It is established that the structural design indicators using the simulation have 4 steps; The indicator of complex space, the diagram of cognitive image, is the analysis of emotion and stimulation, and the dependent variables. Moreover the indicator of complex space is illustrated the connection degree, the symmetry, the axis of sight, and the degree of space division. For the effective analysis, the simulation is to be made matched with the true environment. Thus the simulation has the capability of the objective and correct more than those of true architectural environment. And it could establish immediately the experimental data and response.

The previous literature on the field of performance management mainly focuses on the research regarding the critical success factors, the intention of use, and the output of the BSC system. This paper is to develop and analyze the influencing factors of the acceptance on the BSC performance indicators in the public sector. The result from the analysis of the data collected from this research shows that these influencing factors include the education about BSC, the specificity of the indicators, the connection between strategy and mission, and the participation and support during the development of the indicators. Further, the result reveals that the CEO's concern is nothing to do with the employees acceptance of the BSC performance indicators in the public sector, unlike the consistent result from the previous literature. The reason is because the employees often tend to refuse the performance indicators of the CEO's concern that increase their workload due to the establishment of the excessive target of the indicators and their periodic reports.

As a follow up to the Agenda 21's policy statement for safe management of radioactive waste adopted at Rio Conference held in 1992, the UN invited the LAEA to develop and implement indicators of sustainable development for the management of radioactive waste. The IAEA finalized the indicators in 2002, and is planning to calculate the member states' values of indicators in connection with operation of its Net-Enabled Waste Management Database system. In this paper, the basis for introducing the indicators into the radioactive waste management was analyzed, and calculation methodology and standard assessment procedure were simply depicted. In addition, a series of innate limitations in calculation and comparison of the indicators was analyzed. According to the proposed standard procedure, the indicators for a few major countries including Korea were calculated and compared, by use of each country's radioactive waste management framework and its practices. In addition, a series of measures increasing the values of the indicators was derived so as to enhance the sustainability of domestic radioactive waste management program.

The performance of precast concrete structures is greatly influenced by the behaviour of beam-to-column connections. A single connection may be required to transfer several loads simultaneously so each one of those loads must be considered in the design. A good connection combines practicality and economy, which requires an understanding of several factors; including strength, serviceability, erection and economics. This research work focuses on the performance aspect of a specific type of beam-to-column connection using partly hidden corbel in precast concrete structures. In this study, the results of experimental assessment of the proposed beam-to-column connection in precast concrete frames was used. The purpose of this research is to develop and apply the Extreme Learning Machine (ELM) for moment-rotation prediction of precast beam-to-column connections. The ELM results are compared with genetic programming (GP) and artificial neural network (ANN). The reliability of the computational models was accessed based on simulation results and using several statistical indicators.

As the building structures are higher and bigger, the high-performance steels of high strength, toughness, and low yield ratio had been required and developed. In this paper the behavior of the moment connection with bolted web and high strength steel was studied by using the finite-element analysis computer program of ABAQUS. The analysis model is based on the test results and the same cyclic load history was applied at the FE(Finite Element) model until it failed in the test. Through the FEA, several indicators hardly measured from the test were acquired. These indicators related to stress and strain were selected from three plastic rotation stages: 0.003 rad, 0.03 rad, and final failure rotation. Specifically, at the final failure stage, the strain indicators producing the full plastic behavior were suggested as a mechanical property for steel.
