  • The cabin service quality expected by customers during the air travel can be the top priority to choose an airline. Customers' perception about cabin service quality evaluation are important for developing differentiated cabin service strategies of airlines, so this study aims to analyze the effect of the cabin service quality on airline image and customer loyalty. For achieving this purpose, literature study and empirical study on cabin service, customer loyalty and airline image were performed together. As a results of research, a high level of the cabin service quality provided by airlines significantly influenced positive images of airlines and customer loyalty. And customers' positive image towards airlines practically had a substantial influence on the improvement of customer loyalty. These study results would help in creating positive images of airlines and securing customer loyalty by developing differentiated and improved cabin service quality strategies of each airline in the limitless competition of the aviation service industry.

  • In order for the corporation to get a good image from the customers it should consider several variables, but especially important are corproate ethics and customer satisfaction through quality improvement. Standard multivariate data analysis can be applied to find out the importance of customer satisfaction and corporate ethics as influence factors in the corporate competitive strategy. When applying this Methodology, multivariate normal distributions density function and the identical covariance between groups assumptions have to be satisfied. By using the evaluation result from a small number of specialists in an attempt to decide on the strategical factors that will create a better company image than its competitor, if it chooses to use statistical discriminant analysis method, it would be difficult to satisfy the two assumptions mentioned above. This thesis introduces discriminant analysis method that uses LP/GP effectively which is applicable to this particular situation.

  • Mammography is considered the single most important diagnostic tool in the early detection of breast cancer. Today's dedicated mammographic equipment, specially designed x-ray screen/film combinations, coupled with controlled film processing, produces excellent image quality and can detect very low contrast small lesions. In mammography, it is most important to produce consistent high-contrast, high-resolution images at the lowest radiation dose consistent with high image quality. Some of the major technical development milestones that have let to today's high quality in mammographic imaging are reviewed. Both the American College of Radiology Mammography Accreditation Program and the Mammography Quality Standards Act have significant impact on the improvement of the technical quality of mammographic images in the United States and worldwide. A most recent development in digital mammography has opened up avenues for improving diagnosis.

  • 본 논문은 LCD 모니터 상에서 영상 향상을 위한 콘트라스트 제어방식을 제안하였다. 제안한 방식은 입력되는 필드 혹은 프레임 중에서 화소의 최대 값과 최소 값을 판별하고 이를 이용하여 화면의 개선 정도를 결정한다. 필드 또는 프레임의 메모리가 필요하지 않고, 기존의 방식에 비해 하드웨어 구성이 간단하여 실시간 처리를 요하는 분야에 쉽게 적용 가능하다 또한 입력되는 콘트라스 영역의 가중치 값을 변화시킴으로써 콘트라스트 제어가 가능하다 제안한 방법은 콘트라스트 제어 알고리즘과 룩업 테이블을 이용한 영상의 모드에 따라선택적으로 가중치 기울기를 구간별로 달리하여 개선된 영상을 얻는다. 제안한 다계조 콘트라스트 제어 방식을 컴퓨터 시뮬레이션을 통하여 검증하였으며, 시뮬레이션을 통해 영상을 확인하였다.

  • The authors aimed to analyze the quality improvement efficiency of wound dressing with 2-octyl cyanoacrylate(2-OCA) in stereotactic image guided linear or sigmoid incisions in a cohort of consecutive craniotomy patients, and to compare clinical results with those of iodine-dressing and silk sutured patients underwent conventional craniotomy surgery with large pedicle flap incisions without stereotactic guidance. In methods, 26 patients were involved as the study group at one hospital. We retrospectively compared their results with those of 38 consecutive control patients at the same unit. The suggested new medical material, 2-octyl cyanoacrylate(2-OCA), resultantly decreased or prevented the contaminated fluid influx from scalp outside. The mean infection rate for the control group (7.89%) was relatively higher than that of the study group (3.85%). In addition, the use of stereotactic image guided craniotomy was significant to reduce operation time, to simplify operative procedures and to decrease potential risk factors.

  • DCT or Wavelet based on Image compression technique occurred to compression artifact. In order to remove this problem, we can apply many improvement algorithms. But in these cases, these algolithms resulted in bad results against the good quality image. Therefore this paper proposes an automatic image interpretation technique not to apply to the good quality images. In this paper, we exploit the basic nature of DCT.

  • Images can be contaminated with different types of noise, for different reasons. The neighborhood averaging and smoothing by image averaging are the classical image processing techniques for noise removal. The classical spatial filtering refers to the aggregate of pixels composing an image and operating directly on these pixels. To reduce or remove effectively noise in image sequences, it usually needs to use noise reduction filter based on space or time domain such as method of spatial or temporal filter. However, the method of spatial filter can generally cause that signals of objects as the target are also blurred. In this paper, we propose temporal filter using the piece-wise quadratic function model and enhancement algorithm of image quality for the performance improvement of target detection and tracking by heterogeneous noise reduction. Image tracking simulation that utilizes real IIR(Imaging Infra-Red) images is employed to evaluate the performance of the proposed image processing algorithm.

  • Visibility in underwater images is usually poor because of the attenuation of light in the water that causes low contrast and color variation. In this paper, a new approach for underwater image quality improvement is presented. The proposed method aims to improve underwater image contrast, increase image details, and reduce noise by applying a new method of using contrast stretching to produce two different images with different contrasts. The proposed method integrates the modification of the image histogram in two main color models, RGB and HSV. The histograms of the color channel in the RGB color model are modified and remapped to follow the Rayleigh distribution within certain ranges. The image is then converted to the HSV color model, and the S and V components are modified within a certain limit. Qualitative and quantitative analyses indicate that the proposed method outperforms other state-of-the-art methods in terms of contrast, details, and noise reduction. The image color also shows much improvement.

  • This study aimed to design a strategy in encouraging the loyalty level of priority customers of Sharia banks in Indonesia. The strategy was outlined in a series of alternative applicative programs priority. The use of ANP intended to simplify the existing problems so that the offered solution was easier to apply. Each item was scored on a 5-point Likert scale. The expected outcome was to give priority scales to the offered solutions. The findings of this study are service quality, brand image, bank image which could build customer loyalty in Sharia banks. Priority customer gathering could strengthen the bonds between customers and also between customers and their banks. The excellence of Sharia banks in terms of service quality, brand image, and bank image, when combined with priority customer gathering activities, would become a powerful formula in increasing priority customer loyalty to banks that lead to increased revenue from banks. Originality of this research was the formulation process of a new approach in search of ways to increase the customer loyalty, as well as giving concrete proposals for the banking world in designing customer loyalty improvement programs. This paper shows the updated strategy in Customer Loyalty, Bank image, Brand image, Banking service quality.
