Purpose: This study was done to investigate changes in image of nursing in first year students of nursing after courses on history & philosophy of nursing. Methods: Participants were 100 first year students at a nursing college located in K city. The students were asked to submit a written answer to an open-ended question. Data were collected in March, 2011, before the students started nursing courses, and again in June, 2011, after they had finished one semester of nursing courses. Data were analyzed using Van Kaam's phenomenological method. Results: Before the nursing courses, students regarded nursing as caring for patients comfortably with warmth and kindness, helping patients with self-sacrificing spirit and service, and being tough and overwhelming to do. After finishing one semester of nursing courses, they regarded nursing as a profession that requires motherly care, love and devotion, and as meaningful and beautiful to do. Conclusions: After finishing one semester of nursing courses, the images of nursing held by the students changed from a traditional perspective emphasizing the emotional and negative aspects to one focusing more on the professional and positive aspects. It is essential to establish healthy and positive images of nursing among students through the nursing curriculum.

The purpose of this study was to examine the differences in image perception, and to investigate the differences in age and income inferences according to the wearing of accessories with black dress. A quasi-experimental method was used for this study. The experimental design was a $2{\times}3{\times}3$(necklace${\times}$earrings${\times}$corsage) factorial design. The subjects were 610 female college students residing in Seoul. The model in the stimulus photographs was a woman with straight long hair. She wore a black one-piece dress with round neckline and short sleeves. The findings indicated that the wearing of a necklace enhanced individuality, attractiveness, and cuteness in women. Professionalism and individuality were heightened when she wore an earring. The red corsage enhanced individuality, but it had a negative effect in professionalism. As for the effect on interaction, attractiveness was more highly perceived when both necklace and large earrings were worn without a corsage. The absence of both necklace and earrings led to a low perception of professionalism, attractiveness, and individuality. The wearing of a necklace was more strongly linked to older age and high income than not wearing it, and it was perceived as more youthful if earrings were not worn. As for interactions, the wearing of small earrings and a red corsage was linked to the oldest age.

In this paper we are attempted to quantitative classification of the three object color regions on a RGB image using of an improved ML(Maximum Likelihood) classification method. A RGB color image consists of three bands i.e., red, green and blue. Therefore it has a 3 dimensional structure in view of the spectral and spatial elements. The 3D structural yokels were projected in RGB cube wherefrom the ML method applied. Between the conventionally and easily usable Box classification and the statistical ML classification based on Bayesian decision theory, we compared and reviewed. Using the ML method we obtained a good segmentation result to classify positive cell nucleus, negative cell Nucleus and background un a immuno-histological breast carcinoma image. Hopefully it is available to diagnosis and prognosis for cancer patients.

An electronic paper display was fabricated by injecting electronic ink, including white and black particles coated by positive and negative charge control agents (CCA), respectively, into closed cells surrounded by micro-barriers. These two types of charged, colored particles are easily damaged or their charging value can be changed by the injection process; therefore, the electrical and optical properties of the image panel fabricated by the injection method were estimated in this study. The active particle-loading method, proposed as a new electronic ink injection process, was applied, and the electro-optical properties of the resulting three-electrode-type e-paper image panel were analyzed. The reflection rate of the white image-panel fabricated with our new injection method was 24.7%, while that of the same panel fabricated with a previously reported injection method was 19.8%. In addition, the response time was improved by about five times compared to those reported in other publications.

Image authentication algorithms have to discriminate forged contents in the various critical fields of military, medical services, digital documents. They must ensure perceptual invisibility and fragility against malicious attacks. It is desirable that watermarking algorithms support sufficient insertion capacity and blind feature. And, high reliable algorithms that can eliminate false-positive and false-negative errors are needed in the watermark extraction process. In this paper, we control coefficients of high frequency band in a DCT domain and compensate brightness histogram for high reliability. As a result, we found that the proposed algorithm guarantee various requirements such as perceptual invisibility with high PSNR values, fragility, high reliability and blind feature. In addition, experiment results show that the proposed algorithm can be used steganographic applications by sufficient capacity of watermark.

In the service industry brand was getting more importance in marketing and brand should be researched more. So the purpose of this study was to identify the causal relationships of 'constructs of brand evidence-brand satisfaction-feelings-brand satisfaction-customer loyalty'. In this research constructs of brand evidence were brand image, price (value for money), servicescapes, core service, employee service, and self-image congruence. This research used family restaurants settings using a sample of customers visiting and enjoying menus at family restaurant stores of Youngnam province. A total of 222 questionnaires were analyzed with SPSS/PC+12.0 and LISREL8.30. Empirical results were that firstly, price, core service and employee service affected brand satisfaction and secondly, employee service, core service, servicescape affected postive feelings and thirdly, brand evidence constructs except self-image congruence influenced negative feelings and lastly, brand satisfaction influenced customer loyalty. On the basis of these findings, family restaurant manager should pay much attention to constructs of brand evidence and use these variables to appeal to and understand target market.

Homogeneously aligned nematic liquid crystal modes are representatively the -FFS (fringe-field switching) mode using liquid crystal (-LC) with negative dielectric anisotropy, the +FFS mode and the IPS (in-plane switching) mode using +LC with positive dielectric anisotropy. In view of image quality evaluation standard of LCD, we compared characteristics of the brightness, the contrast ratio (CR) and color shift when the modes have respectively optimized phase retardation values $(d{\Delta}n)$. Consequently, in the most sensitively viewing angle of a man's physical vision, both FFS modes have advantage over the IPS mode from the brightness & the CR point of view. We are also confirmed that the +FFS mode out of them shows the smallest color shift according to all viewing directions in grey levels.

Multi-temporal satellite imagery can be changed into a transform image that emphasizes the changed area only through the application of various change detection techniques. From the transform image, an automated change detection model calculates the optimal threshold value for classifying the changed and unchanged areas. However, the model can cause undesirable results when the histogram of the transform image is unbalanced. This is because the model uses a single threshold value in which the sign is either positive or negative and its value is constant (e.g. -1, 1), regardless of the imbalance between changed pixels. This paper proposes an advanced method that can improve accuracy by applying separate threshold values according to the increased or decreased range of the changed pixels. It applies multiple threshold values based on the cumulative producer's and user's accuracies in the automated binary change detection model, and the analyst can automatically extract more accurate optimal threshold values. Multi-temporal IKONOS satellite imagery for the Daejeon area was used to test the proposed method. A total of 16 transformation results were applied to the two study sites, and optimal threshold values were determined using accuracy assessment curves. The experiment showed that the accuracy of most transform images is improved by applying multiple threshold values. The proposed method is expected to be used in various study fields, such as detection of illegal urban building, detection of the damaged area in a disaster, etc.

The study explores the factors affecting the brand selection behavior of retail chains in Vietnam and to what extent they have an impact on the customer's choice intention. This research employs a combination of both qualitative and quantitative mixed methods with the help of SPSS version 22.0 in data analysis. Expert interviews are used to design the questionnaire for the survey conducted on 700 consumers. Research results show that the eight factors of store image (1-to-3 split factor of store image including the display of goods and services), price perception, risk perception, brand attitude, brand awareness, and brand familiarity were determined. They all influence the intention to choose the retail chain brand. With a positive β coefficient, the more store image, price perception, brand attitude, and brand awareness are enhanced, the more likely the intention to choose the retail chain brand. The factor of risk perception has negative ��, resulting in an inverse impact on choosing a retail chain brand name. Price perception and risk perception have the strongest impact on retail chain decision behavior while commodity display factors the least. Based on these important results, the study proposes implications for retailers and manufacturers.
