The purpose of this study was to investigate the influence of luxury brand value on luxury brand preferences according to chemyon(social-face). For data collection, research questionnaires were responded by 222 females over 20 years old consumers living in Pusan and Ulsan. The collected data were analyzed using SPSS 14.0 for windows Package by frequency analysis, the factor analysis using Varimax, reliability analysis, multi-regression analysis, and chow-test. The results of this study were as follows: First, concerning the worth of luxury brands that qualify value, conspicuous value, unique value, and emotional value significantly affected the consumers' luxury brand preferences. On the other hand, only social value of the luxury brand did not have a significant effect on the consumers luxury brand preferences. Second, the study was to investigate whether the luxury brand value has an effect on the brand preferences according the consumer's chemyon or not. The results showed different effects of perceived values on luxury brand preferences between the low chemyon group and the high chemyon group. The high chemyon group had an effect on conspicuous value, social value, and emotional value, while the low chemyon group had an effect on quality value for luxury brand preference.

This paper proposes a Web Based Online Outage Cost Assessment and Information System(WOOCAIS) for power system outage cost assessment. The proposed WOOCAIS is a kind of web based survey method for outage cost assessment. While conventional survey methods have done outage cost assessment based on survey paper lists collected by post mail or visiting customers, the proposed WOOCAIS is a web based online survey operation and assessment system. Therefore, it can curtail expenditure for survey and also is more convenient than conventional method. It will be set up for actual outage cost assessment system of KEPCO in South Korea in the near future. The WOOCAIS will be applied in various research and actual planning and operation areas. First of all, the assessed results may be not only applied as one of objective function for generation system and grid expansion but also operational planning problems in power system.

The mechanical system of a drive can often be modeled as a two- or three-mass-system. The load is coupled to the driving motor by a shaft able to perform torsion oscillations. For the automatic tuning of the control, it is necessary to know the mathematical description of the system and the corresponding parameters. As the manpower and setup-time necessary during the commissioning of electrical drives are major cost factors, the development of self-operating identification strategies is a task worth pursuing. This paper presents an identification method which can be utilized for the assisted commissioning of electrical drives. The shaft assembly can be approximated as a two-mass non-rigid mechanical system with four parameters that have to be identified. The mathematical background for an identification procedure is developed and some important implementation issues are addressed. In order to avoid the excitation of the system with its natural resonance frequency, the frequency response can be obtained by exciting the system with a Pseudo Random Binary Signal (PRBS) and using the cross correlation function (CCF) and the auto correlation function (ACF). The reference torque is used as stimulation and the response is the mechanical speed. To determine the parameters, especially in advanced control schemes, a numerical algorithm with excellent convergence characteristics has also been used that can be implemented together with the proposed measurement procedure in order to assist the drive commissioning or to achieve an automatic setting of the control parameters. Simulations and experiments validate the efficiency and reliability of the identification procedure.

High-fidelity nuclear data libraries and neutronics simulation tools are essential for the development of fast reactors. The IAEA coordinated research project on "Neutronics Benchmark of CEFR Start-Up Tests" offers valuable data for the qualification of nuclear data libraries and neutronics codes. This paper focuses on the verification and validation of the CEFR start-up modelling using OpenMC Monte-Carlo code against the experimental measurements. The OpenMC simulation results agree well with the measurements in criticality, control rod worth, sodium void reactivity, temperature reactivity, subassembly swap reactivity, and reaction distribution. In feedback coefficient evaluations, an additional state method shows high consistency with lower uncertainty. Among 122 relative errors in the benchmark of the distribution of nuclear reaction, 104 errors are less than 10% and 84 errors are less than 5%. The results demonstrate the high reliability of OpenMC for its application in fast reactor simulations. In the companion paper, the influence of cross-section libraries is investigated using neutronics modelling in this paper.

In study I, Domain-Specific Risk Taking Scale(DOSPERT) was translated into Korean and was validated that it had 6 factors structure and showed adequate reliability and validity, using the data had been collected from 438 participants. In study 2, two research problems were examined using the data had been collected from 497 participants who were different from study I. First, the mediation effect of sensation seeking and perceived benefit on the relationship between narcissism and risk-taking were examined. Using path analysis, it found that sensation seeking and perceived benefit mediated the relationship between NPI narcissism and risk-taking fully, and between PNI narcissism and risk-taking partially. Seceond, the moderate effect of contingencies of self-worth(CSW) on the relationship between perceived benefit-risk and risk-taking was examined. Using multi-group analysis, it found that virtue CSW moderated the relationship between perceived benefit-risk and total risk-taking, various CSWs moderated the relationships between perceived benefit-risk and 6 sub domains of risk-taking. These results were compared with previous studies of risk-taking and discussed the relevance of the narcissistic type.

The influences of sporting shoe brands wants to exert on consumers in the sports shoe market has been tried in many forms, and its effectiveness has also been proven. A variety of marketing strategies are being proven by each brand that they consider to be worth using. However, marketing strategies using sports shoe collectors have never been empirically proven in their influence. This is because the collecting behaviors shown in the traditional sports shoe market is very low in comprehension. This study was initiated by critical thought that determined a new marketing strategy was needed in the sports shoe market, which is considered to be somewhat limited, and is aimed at setting and demonstrating the path to influence in establishing a marketing strategy using sports shoe collectors. To achieve the purposes of this study, 231 consumers who were exposed to stimuli for describing the products of a hypothetical sports shoe collectors were used. For data analysis, frequency analysis, reliability analysis, correlation analysis, and confirmative factors analysis and structural equation method using PASW 21.0 and AMOS 20.0 were used. Based on the results derived from this study, we have found a new path to a new marketing strategy based on the expertise held by sports shoe collectors in the sports shoe market, which we hope will serve as one of the new growth engines for the sluggish sports shoe market in Korea.

The Pressurized water reactor owners group (PWROG) developed and applied a risk-informed in-service inspection (RI-ISI) program, as an alternative to the existing ASME Section XI' sampling inspection method. The RI-ISI programs enhance overall safety by focusing inspections of piping at high safety significance (HSS) locations where failure mechanisms are likely to be present. Additionally, the RI-ISI program can reduce nondestructive evaluation (NDE) exams, man-rem exposure for inspectors, and inspection time, among other benefits. The RI-ISI method of in-service piping inspection was applied to 3 units (KSNPs: Korea standard nuclear power plants) and is being deployed to the other units. In this paper, the results of RI-ISI for a Framatome type (France CPI) nuclear power plant are presented. It was concluded that application of RI-ISI to the plant could enhance and maintain plant safety, as well as provide the benefits of greater reliability.

Probabilistic safety assessment (PSA) has had a significant role in quantitative decision-making by finding design and operational vulnerabilities and evaluating cost-benefit in improving such weak points. In particular, it has been widely used as the core methodology for risk-informed applications (RIAs). Even though the nature of PSA seeks realistic results, there are still "conservative" aspects. One of the sources for the conservatism is the assumptions of safety analysis and the estimation of failure frequency. Surveillance, diagnosis, and prognosis (SDP), utilizing massive databases and information technology, is worth highlighting in terms of its capability for alleviating the conservatism in conventional PSA. This article provides enabling techniques to solidify a method to provide time- and condition-dependent risks by integrating a conventional PSA model with condition monitoring and prognostics techniques. We will discuss how to integrate the results with frequency of initiating events (IEs) and probability of basic events (BEs). Two illustrative examples will be introduced: (1) how the failure probability of a passive system can be evaluated under different plant conditions and (2) how the IE frequency for a steam generator tube rupture (SGTR) can be updated in terms of operating time. We expect that the proposed model can take a role of annunciator to show the variation of core damage frequency (CDF) depending on operational conditions.
