This study was conducted to identify the differences in service quality between Incheon and Kimpo international airports and critical factors influencing satisfaction of their customers. According to the results of the study, all service quality factors of Incheon international airport except the service factor of geographical location were better than those of Kimpo international airport. However, all service quality factors of the two airports were evaluated inferior to those of American, western European and Japanese international airports. In addition the service quality factors such as response, safety, airport facility and geographical location were found as critical factors influencing satisfaction of the airport customers. The service quality factor of geographical location of Incheon international airport was measured much inferior comparing with other service quality factors. Thus, the results of this study suggest that the Korean government deliberate and benchmark the international airports of western Europe and the USA in determining the geographical location when planning new international airports.

Service quality research has been the subject of service studies for many years. This study is an exploratory study to improve the service quality measurement factor, and the research has been carried out reflecting the nature of the service; relationship quality, interactivity, horizontality, and harmony. Also, among the developed service quality measurement factors, the research model is reconstructed considering the major factors such as environmental quality, result quality, and convenience quality. Relationality and interactivity redesigned the quality factor, which is called interactive quality. The redesigned service quality factors consisted of interaction quality, result quality, environmental quality, convenience quality, harmonious quality, and horizontal quality. Experimental group evaluation was conducted on the quality factors and 18 measurement items were derived. A questionnaire was conducted to verify the validity of the 18 items. As a result of the questionnaire analysis, 6 factors and 15 items among the 18 items of service quality measurement factor were found valid. The six factors for the service quality measurement presented in this study are the results of the early stage research, but they can be used to improve the service quality factor in the future. However, this is significant because it reflects the characteristics of services that are consistent with the service economy. In particular, the horizontal quality and harmony quality factors are new factors not mentioned in the previous studies and need to be verified through further detailed studies. Further research is needed to improve the service quality measurement factors reflecting the nature of services and the characteristics of new services.

This paper proposes a quality measurement model for video phone service over IP environment. Proposed model enhances conventional E-Model by using quality analysis and this model is suitable for ubiquitous environment. This research measures video phone quality by applying bust packet loss and recency effect. It uses delay and recency effect for compensating actual quality and recognized quality of user using NR and UR factor. Simulation results show that this model can provide more precise results than conventional model by considering recency effect of video phone service quality measurement model.

Background: This study was planned in an attempt to develop a scale for the quality of life in pediatric oncology patients aged 7-12, with child and parents forms. Materials and Methods: In collecting the study data, we used the Child and Parent Information Form, Visual Quality of Life Scale, Scale for Quality of Life Pediatric Oncology Patients Aged 7-12 and the Scale for the Quality of Life in Pediatric Oncology Patients Aged 7-12 for Parents. We also used Pearson correlation analysis, the Cronbach alpha coefficient, factor analysis and ROC analysis for the study data. Results: In this study, the total Cronbach alpha value of the parent form was 0.96, the total factor load being 0.54-0.90 and the total variance explained was 82.5%. The cutoff point of the parent form was 93 points. The total Cronbach alpha value for the child form was 0.96, with a total factor load of 0.55-0.91 and the total variance being explained was 78.3%. The cutoff point of the child form was 65 points. Conclusions: This study suggests that the Scale for Quality of Life in Pediatric Oncology Patients Aged 7-12 Child and Parents Forms are valid and reliable instruments in assessing the quality of life of children.

In this paper, an index for the evaluation of a vehicle intake booming noise and intake sound quality were developed through a correlation analysis and a multiple factor regression analysis of objective measurement and subjective evaluation data. At first, an intake orifice noise was measured at the wide-open throttle test condition. And then, an acoustic transfer function between intake orifice noise and interior noise at the steady state condition was estimated. Simultaneously, subjective evaluation was carried out with a 10-scale score by 8 intake noise and vibration expert evaluators. Next, the correlation analysis between the psychoacoustic parameters derived from the measured data and the subjective evaluation was performed. The most critical factor was determined and the corresponding index for intake booming noise and sound quality are obtained from the multiple factor regression method. And, the optimal design of intake system was studied using the booming noise and the sound quality evaluation index for expectation performance of intake system. Conclusively, the optimal designing parameters of intake system from noise level and sound quality whose point of view were extracted by adapting comparative weighting between the booming noise and sound quality evaluation index, which optimized the process. These work could be represented guideline to system engineers, designers and test engineers about optimization procedure of system performance by considering both of noise level and sound quality.

In this work, small-size, high-performance solenoid-type RF chip inductors utilizing a low-loss Al$_2$O$_3$core material were investigated. The size of the chip inductors fabricated in this work were 15$\times$10$\times$0.7㎣, 2.1$\times$1.5$\times$10㎣, and 2.4$\times$2.0$\times$1.4㎣ and copper (Cu) wire with 40 ㎛ diameter was used as the coils. High frequency characteristics of the inductance, quality factor, and impedance of developed inductors were measured suing an RF Impedance/Material Analyzer (HP4291B with HP16193A test fixture). It was observed that the developed inductors with the number of turns of 7 have the inductance of 33 to 100nH and exhibit the self-resonant frequency (SRF) of .26 to 1.1 GHz. The SRF of inductors decreases with increasing the inductance and the inductors have the quality factor of 60 to 80 in the frequency range of 300 MHz to 1.1 GHz. In this study, small-size solenoid-type RF chip inductors with high inductance and high quality factor were fabricated successfully. It is suggested that the thin film-type inductor is necessary to fabricate the smaller size inductors at the expence of inductance and quality factor values.

The object of this study is to evaluate the factors affecting the water quality and to propose the influence of dominant factor quantitatively. The correlation analysis was performed to know the correlationship among the water quality items As a result of partial correlation analysis, it was shown that the water quality items are affected by the rainfall item directly. The factor analysis was performed to grasp some number of factors on each point for deducing the items of similar variable characteristics. The four points were divided into different factor groups. It was grasped that $NH_3-N$ and $NO_3-N$ Items have different variable characteristics after comparing the items. The Multiple regression analysis can decrease the number of observation. In the deduced multiple regression formula, it was shown that the rate of T-N, $NH_3-N$ and $NO_3-N$ in the independent variable took about 60% among all the regression formulas.
