The purpose of this research is to provide the apparel companies with a successful business strategy by analyzing the concept, function and current status of mileage programs; and examining how customer's attitude, recognition, experience, compensation method of the mileage program in apparel companies affect its brand loyalty. In this research simple random sampling was performed. The sample pool was based on 494 people which included college students and employed men and women in their twenties and thirties living in Seoul and in the metropolitan area. The data analysis was completed on the basis of SPSS package, using frequency, percentage, mean, standard deviation, factor analysis, variation, Scheffe test, regression, t-test, and X/sup2/. The following results were found in this research: It is effective to maintain brand loyalty through continuous relationship with consumers as fierce competition increases in apparel companies. A mileage program is a win/win strategy that allows clothing companies to increase its sales and brand loyalty while consumers feel greater satisfaction.

This paper presents a new dynamic approach for assessing feasibility associated with the implementation of accident management strategies by the operators. This approach includes the combined use of both the concept of reliability physics and a dynamic event tree generation scheme. The reliability physics is based on the concept of a comparison between two competing variables, i.e., the requirement and the achievement parameter, while the dynamic event tree generation scheme on the continuous generation of the possible event sequences at every branch point up to the desired solution. This approach is applied to a cavity flooding strategy in a reference plant, which is to supply water into the reactor cavity using emergency fire systems in the station blackout sequence. The MAAP code and Latin Hypercube sampling technique are used to determine the uncertainty of the requirement parameter. It has been demonstrated that this combined methodology may contribute to assessing the success likelihood of the operator actions required during accidents and therefore to developing the accident management procedures.

Statistical Process Control (SPC) is recognized as one of the most important tool of quality control (QC), and is one research focus in order to implement SPC quickly and effectively using computer technology and network environments. This paper proposes the principle and topology of embedded SPC based on the Internet/lntranet, emphatically discusses the embedded data sampling block, embedded network interface and SPC strategy. An example of application is given.

This study was conducted to explore the coping strategy of Korean men in an international marriage. To achieve this purpose, we selected 4 Korean husbands who had married after seeking the services of matchmaking agencies, and we used snowball sampling. The data were collected through in-depth interviews, and analyzed according to the case study research method. It was found that the men considered international marriage to be their second choice instead of the best one. But they considered their marriage to be 'a prepared marriage', not 'a rash marriage.' 'The prepared marriage' allowed them to have realistic expectations, and to become 'tied in wedlock' with 'a good person.' The Korean husbands coped with difficulties and problems through flexible thinking, such as considering 'how the woman acts depends on the man', 'finding a model mentor couple', 'keeping an open mind to each other', 'reinforcing family ties', and 'developing their wife's independent capacity.' Based on the results, practical alternatives for Korean husbands were suggested. Lastly, the limitations of this study were mentioned.

This paper discusses the composition of the theory of reinforcement teaming, which is applied in real-time teaming, and evolutionary strategy, which proves its the superiority in the finding of the optimal solution at the off-line teaming method. The individuals are reduced in order to team the evolutionary strategy in real-time, and new method that guarantee the convergence of evolutionary mutations are proposed. It is possible to control the control object varied as time changes. As the state value of the control object is generated, applied evolutionary strategy each sampling time because of the teaming process of an estimation, selection, mutation in real-time. These algorithms can be applied, the people who do not have knowledge about the technical tuning of dynamic systems could design the controller or problems in which the characteristics of the system dynamics are slightly varied as time changes. In the future, studies are needed on the proof of the theory through experiments and the characteristic considerations of the robustness against the outside disturbances.

The purpose of this paper is to investigate the effects of fuel injection strategy and engine load on the structure and emissions characteristics of a DI diesel engine with 1.6L of piston displacement. In order to analyze the particulate matter (PM) and exhaust emissions characteristics in a direct injection diesel engine, the quantity of PM and exhaust emissions (including HC, CO and $NO_X$) were investigated under various injection strategies and engine loads. Two different injection strategies (one pilot/main injection and two pilots/main injection) was investigated under the various engine loads. A thermophoretic sampling method with a scanning electron microscope (SEM) were used to obtain the PM morphology (including primary particles, the size of the agglomerates, the number of agglomerates, the fractal dimension). The quantity of soot gradually increased with increasing engine load at both injection strategies. The primary particles in the PM agglomerates indicate that the average of the primary particle and radius of gyration increased as the engine load increased.

In this paper, a three phase PWM AC to DC boost converter that operates with unity power factor and sinusodial input currents si presented. The current control of the converter is based on the space vector PWM strategy with fixed switching frequency and the imput current tracks the reference current within one sampling time interval. Space vector PWM strategy for current control was materialized as a digital control method by using DSP. By using this control strategy low ripples in the output voltage, low harmonics in the input current and fast dynamic responses are achieved with a small capacitance in the dc link.

This paper proposes a simple control strategy based on the discontinuous PWM(DPWM) to balance the DC-link voltage of three-level Neutral-Point-Clamped(WPC) inverters at low modulation index. New DPWM methods in multi-level inverter are also introduced. The proposed DPWM method changes the path and duration to flow the neutral point current out of or into neutral point of the DC-link and it makes the overall fluctuation of the DC-link voltage zero during a sampling time of reference voltage vector. Therefore, the voltage of the DC-link can be balanced fairly well and also the voltage ripple of the DC-link is reduced significantly. Moreover, comparing with conventional methods, the proposed strategy is very simple. The validity of the proposed DPWM method is verified by experiment

Purpose: This study aims to explain the effect distribution strategy and competitiveness of entrepreneurial personality on marketing capabilities and performance, the effect of marketing capabilities on marketing performance, the role of marketing capabilities as a mediating variable on the effect of entrepreneurial personality on marketing performance, and the role of credit access moderating effect of entrepreneurial personality on marketing capabilities and performance. Research design, data, and methodology: This research was conducted in Bali, on a small clothing industry. The sample size was set at 150 respondents, using a cluster random sampling approach. Data were analyzed using descriptive analysis techniques and partial least square. Result: The findings show that; entrepreneurial personality and marketing capabilities have a significant effect on marketing performance, entrepreneurial personality has a significant effect on marketing capabilities. Another result shows that marketing capability mediates the effect of entrepreneurial personality on marketing performance, access to credit acts as a moderating predictor, and as quasi moderating the effect of entrepreneurial personality on marketing performance. Conclusions: Entrepreneurs should try to increase their knowledge and skills in marketing formally or informally. Competence in terms of individual knowledge and skills can indicate social capital investment, which indirectly contributes to one's mindset and insight.
