A concession business at Incheon Int'l airport has achieved a huge success since its grand opening of 2001. However the duty-free market became matured due to downtown duty free stores and on-line stores. Thus this paper tried to research and suggest strategic planning of VMD at Incheon airport's duty-free after analyzing the relationship among the components of duty-free store's VMD, brand awareness, brand image and customer's loyalty. Components of VMD are constructed in harmony, attractiveness, trendiness and Trust, which are independent variables. In addition, brand awareness and brand image are chosen as control variables. Customer loyalty is also designated as a dependant variable. Focusing those variables, this paper tried to find out the effect of VMD components to brand and consumer loyalty. According to the research result, it is proven attractiveness and harmony have a significant positive impact on brand awareness and brand image. It is also found out brand awareness and image have a positive impact on passenger's loyalty on duty-free stores at Incheon airport.

In this study, an analysis is conducted to understand the effect of the cabin crew's image-making autonomy on job enthusiasm, service performance and organizational performance. And this is conducted on cabin crew members in airlines with autonomy based on image making standards and a total of 109 copies are used for final analysis. First, the image-making autonomy show significant positive (+) influence on all of the sub-factors of job enthusiasm such as job vitality, job commitment, and job commitment. Second, all sub-factors of job enthusiasm, job vitality, job commitment and job commitment show a significant positive (+) influence on service performance. Third, service performance show a significant positive (+) influence relationship on organizational performance. As a result, it is expected that airlines will be used as a basis for easing the regulations for image making of cabin crew and introducing an autonomous management system in the future.

Purpose - This study's aims are to examine the effects of airline service quality on brand image, brand attitude and reuse intention and the mediating roles of brand image and brand attitude in the relationship between airline service quality and reuse intention. Research design, data and methodology - A total of 500 questionnaire copies were distributed and 474 were used for the empirical study after excluding some empirical inappropriate or unusable ones. To analyze the collected data, the SPSS/WIN 22.0 statistical package was used. Results - The result of analysis showed that all the intangible, tangible and human elements of the airline service quality positively influenced on brand image and brand attitude and did not directly influence on reuse intention. However, brand image and brand attitude played mediating roles in the relationship between all the service quality elements and reuse intention. Conclusions - This means that airlines need to develop service quality, which is differentiated and provides special feelings for customers and work out improvement strategies for positive brand images and attitudes, since customers choose and reuse airlines, based on brand images and attitudes, which are perceived and formed through the experience of airline service quality and word of mouth.

Despite rapid growing in domestic duty free industry, weight of income from airport duty free area is relatively decreasing because of rapid progress in downtown duty free area. The purpose of this research was investigating the relationship between airport duty free servicescape and its effects on customer satisfaction and image for duty free shop, in order to maintain own competitive advantages. In pursuing above, previous studies related to servicescape, service value, customer satisfaction, and image were examined for literature review. Based on this previous studies, research model were constructed. Hypothesis was verified by effect. Data from 305 samples was employed for final survey. The main results show that functionality, attraction and convenience were meaningful factors to effect perceived servicescape. On the other hand, cleanness and comfort had few or no influence on servicescape. The perceived servicescape affected on service value and customer satisfaction. Service value had positive effects on customer satisfaction which was discovered to affected on image for duty free shop.

This research examines the affect of destination image factors on revisit intention of domestic tourists at Ba Ria Vung-Tau (BRVT), by questioning directly 510 domestic tourists. The convenient sampling method is used in dividing the crowds into four groups; the four main surveyed areas in BRVT are: Vung Tau, Long Hai-Phuoc Hai, Xuyen Moc and Con Dao. A combination of qualitative and quantitative methodologies were utilized.A focus group of 10 domestic tourists wasset up to review and explore the variousfactors as well as the conceptual model. An in-depth interview with 12 participants was developed to fine-tune measurement items. The questionnaire applied a 5-point Likert scale. Checking the reliability by Cronbach's Alpha, exploratory factor analyzing and linear multiple regression were used with the SPSS program. The results show that there are eight main destination image factors affecting domestic tourists revisit intention to BRVT using linear regression and arranged by decreasing importance: Infrastructure, Variety Seeking, Accessibility, Local food, Atmosphere, Environment, Price Value, Leisure and Entertainment. From that, the research offers some suggestions and policy recommendations for the tourism business and provincial policy-makers to identify the main issues and develop better customer services to increase domestic tourists'revisit intention.

In this paper, we propose a motion control scheme of robot manipulators based on visual feedback under camera-in-hand configuration. The desired joint velocity and acceleration for motion control is made by the feature-based visual data in the outer loop. The control input for tracking feature points on the image plane uses robot kinematics dynamic. The proposed control input consists of the image feature and the joint velocity error to achieve robustness to the parametric uncertainty. The stability of the closed-loop system is proved by Lyapunov approach. Computer simulations and experiments on a two degree of freedom manipulator with 5 links are presented to illustrate the performance of proposed control system.

The runway visual range is one of the important factors that decide the possibility of taking offs and landings of the airplane at local airports. The runway visual range is affected by weather conditions like fog, wind, etc. The pilots and aviation related workers check a local weather forecast such as runway visual range for safe flight. However there are several local airfields at which no other forecasting functions are provided due to realistic problems like the deterioration, breakdown, expensive purchasing cost of the measurement equipment. To this end, this study proposes a prediction model of runway visual range for a local airport by applying convolutional neural network that has been most commonly used for image/video recognition, image classification, natural language processing and so on to the prediction of runway visual range. For constituting the prediction model, we use the previous time series data of wind speed, humidity, temperature and runway visibility. This paper shows the usefulness of the proposed prediction model of runway visual range by comparing with the measured data.

This paper has been studied a wavelet based still image transmission over the wireless channel. EZW(Embedded Zerotree Wavelet) is an efficient and scalable wavelet based image coding technique, which provides progressive transfer of signal resulted in multi-resolution representation. It reduces therefore the reduce cost of storage media. Although EZW has many advantages, it is very sensitive on error. Because coding are performed in subband by subband, and it uses arithmetic coding which is a kind of variable length coding. Therefore only 1∼2bit error may degrade quality of the entire image. So study of error localization and recovery are required. This paper investigates the use of reversible variable length codes(RVLC) and data partitioning. RVLC are known to have a superior error recovery property due to their two-way decoding capability and data partitioning is essential to applying RVLC. In this work, we show that appropriate data partitioning length for each SNR(Signal-to-Noise Power Ratio) and error localization in wireless channel.
