  • In this research, customized management performance index for small and medium enterprises in solar energy area was developed. To acquire management performance index, first Delphi technique is applied and secondly, AHP(Analytic Hierarchy Process) used to give weight to each main index and then final management performance index was achieved. By developing management performance index, top management could manage their company more efficiently.

  • In recent years, interests and studies on the urban regeneration projects have been increased and largely conducted. It is a part of the effort that solves some social and economical problems occurred by deteriorated buildings and degraded infrastructures through new urban regeneration projects or redevelopment projects. However, the urban regeneration projects show the characteristics that can not guarantee in the project performance because the projects have various and complex stakeholders related to these projects and are exposed to lots of risks due to its huge scale. This study proposed the risk performance index method to improve the efficiency of the overall performance measurement for a mega-project by extending from the traditional cost/schedule based performance measurement system. The risk performance index method proposed in this study has a similar system to the EVMS, and makes possible to perform a three dimensional integrated performance measurement in cost/schedule/risk through 18 different indexes that compose the risk performance index.

  • The concept of improved performance indicators (PIs) for use in the KINS Safety Performance Indicator (SPI) program for reactor safety area is proposed in this paper. To achieve this, the recently developed PIs from the USNRC that use risk information were investigated, and a feasibility study for the application of these PIs in Korean NPPs was performed. The investigated PIs are Baseline Risk Index for Initiating Events (BRIIE), Unplanned Scrams with Complications (USwC), and Mitigating System Performance Index (MSPI). Moreover, the thresholds of the existing safety performance indicators of KINS were evaluated in consideration of the risk and regulatory response to different levels of licensee performance in the graded inspection program.

  • Purpose. This study was conducted from the period of April 12th, 2017 to April 26th, 2017. The questionnaires were distributed among a group of 76 adults aged 20 years or older, who participated in the prevention program of the department of dental hygiene at Busan Metropolitan City. The negative questionnaire was finally analyzed. Methods. The SPSS program was used for analysis of this study. The general characteristics of the subjects were t-test and one-way, ANOVA(by Scheffe post-test) for a PHP index (Patient Hygiene Performance index) according to frequency analysis, general characteristics, smoking and drinking behavior, and dietary behavior. Results. As a result of an examination of the PHP index(Patient Hygiene Performance index) ac- cording to smoking and drinking behavior, the amount of alcohol drunk was statistically higher than that of 'soju that was not drunk'(P<0.05). As a result of the PHP index (Patient Hygiene Performance index) according to dietary behavior, 'vegetarians' were statistically higher than 'Carnivorous oriented' individuals (P<0.05). Moreover, individuals who regularly 'drank almost no water' were statistically significantly higher than those who 'drank water steadily'.(P<0.05). Conclusion. As a result, appropriate management is required for oral health of the patient, Oral health education is needed to systematically consider smoking, drinking, and eating habits when taking into consideration the individual oral environment.

  • Purpose: This study examined whether or not changes in the static and dynamic balance performance occur during pregnancy. Methods: Fourteen pregnant women and fourteen non-pregnant women volunteered to participate in the study. All subjects were tested for their balance performance on the Chattecx Balance System (Chattanooga Group, Inc., USA) under a two platform condition: stable platform and dynamic platform(forward-backward sliding and tilting). The Chattecx Balance System was measured using the postural sway index, anterior-posterior sway index, and medial-lateral sway index. Results: There was a significant difference in the postural sway index and anterior posterior sway index in the static and dynamic platform condition between the pregnant and non-pregnant women (p<0.05). However, there was no difference in the medial-lateral sway index. Conclusion: The postural sway index and anterior-posterior sway index decreases during pregnancy.

  • The electric power industry throughout the world is undergoing considerable changes from the vertically integrated utility structure to the deregulated market. However, the deregulated electricity market is operated with respect to theory of economical efficiency, and therefore, the system operator requires data with fast contingency ranking for security of the bulk power system. This paper compares the weather dependant probabilistic risk index(PRI) with the system performance index for power flow in the IEEE-RTS. The system performance index for power flow presents the power system stability. This paper presents fast calculation method for determining contingency ranking using the weather dependant probabilistic risk index(PRI). The probabilistic risk index can be classified into the case of normal and adverse weather. This paper proposes calculation method using the probabilistic risk index in determining contingency ranking required for security under the deregulated electricity market.

  • The authors have shown that the performance of discrete-time observer-based monitoring systems can be represented by the performance index k$_2$(P) (condition number of the eigensystem P of the observer matrix in terms of L$_2$ norm). The observers with the minimized performance index can be defined as robust observers in the sense that the observer performance can be guaranteed in harsh environments. In this paper, based on the performance index, a design methodology for the robust discrete-time observer is developed. Similar to the continuous-time case, the methodology determines the structure and eigenvalues of the observer matrix simultaneously. A complete design procedure is given for single-output case and is illustrated with a spindle-driver example. The simulation results demonstrate the improved performance compared with a traditional pole-placement observer technique.
