Quantitative Evaluation of Image Quality using Automatic Exposure Control This it leads, the relationship of control and image between of photographing condition, DR proper use method proposing. Chest phantom acquires Chest PA images which it follows in conditional change, Image evaluation factor (SNR (Signal to Noise Ratio), CNR (Contrast to Noise Ratio), PSNR (Peak Signal to Ratio), RMS (Root Mean Square)). It excepted RMS price, SNR, CNR, PSNR the case which uses AEC it came out being high The fact that the quality of image is better there was a case which does not use AEC. but Price it was slight. Image qualitative it was deficient in AEC use presence. Through this, the overall situation and most efficient use of radiation workers is better suited. But Passive AEC use would be appropriate for use rather than proactive AEC.

Objectives To examine the relationship between health-related quality of life (HRQoL) and body mass index (BMI) of obese children. Methods This cross-sectional study included 387 children. HRQoL was measured with the PedsQLTM 4.0 Generic Core Scale. BMI was classified according to the World Health Organization Asia-Pacific obesity guidelines. Psychosocial factors (body image, self-esteem, and depression/anxiety) were also measured. Data were analyzed using one-way analysis of variance, Pearson's correlation and Path analysis. Results Obese participants reported lower score for physical evaluation, self-esteem, appearance evaluation component of body image, total HRQoL score, and physical/emotional/social function components of HRQoL ; they reported higher score for depression/anxiety. In addition, results indicated that as BMI increased, appearance evaluation, total HRQoL score, and social function component of HRQoL dropped. Path analysis revealed that BMI did not directly affect HRQoL ; however, BMI directly affects body image and self-esteem, indirectly mediates depression/anxiety, and thereby impacts on an individual's HRQoL. Conclusions Body image and self-esteem, rather than BMI itself, have more influence on HRQoL. This reinforces the importance of therapeutic intervention to enhance body image and self-esteem among obese children.

In ultrasound telemedicine, it is important to reduce the size of the data by compressing the ultrasound image when sending it. Ultrasound images can be divided into image context and other information consisting of patient ID, date, and several letters. Between them, ultrasound context is very important information for diagnosis and should be securely preserved as much as possible. In several previous papers, ultrasound compression methods were proposed to compress ultrasound context and other information into different compression parameters. This ultrasound compression method minimized the loss of ultrasound context while greatly compressing other information. This paper proposed the method of automatic segmentation of ultrasound context to overcome the limitation of the previously described ultrasound compression method. This algorithm was designed to robust for various ultrasound device and to enable real-time operation to maintain the benefits of ultrasound imaging machine. The operation time of extracting ultrasound context through the proposed segmentation method was measured, and it took 311.11 ms. In order to optimize the algorithm, the ultrasound context was segmented with down sampled input image. When the resolution of the input image was reduced by half, the computational time was 126.84 ms. When the resolution was reduced by one-third, it took 45.83 ms to segment the ultrasound context. As a result, we verified through experiments that the proposed method works in real time.

Purpose: To clarify the relationship between the diameter of the simulated bead and the Z-resolution of the tomosynthesis image. Methods: A simulated bead was placed on a 1,024×1,024×1,024-pixel base image. The diameters were set to 0.025, 0.05, 0.1, 0.2, 0.3, 0.7, 1.0, and 1.3 mm. A bead was placed at the center of the base image and projected at a simulated X-ray angle range of ±45° to obtain a projected image. A region of interest was placed at the center of the bead image and the slice sensitivity profile (SSP) was obtained by acquiring pixel values in the z-direction. The full width at half maximum of the SSP was defined as the Z-resolution and the frequency response was obtained by the 1-D Fourier transform of the SSP. Results: Z-resolution increased with increasing bead diameter. However, there was no change in Z-resolution between 0.025 and 0.1 mm. The frequency response was similar to that of the Z-resolution, with a significant difference between 0.1 and 0.2 mm diameter. Conclusions: Z-resolution is dependent on the diameter of the bead, which should be selected considering the pixel size of the tomosynthesis image.

Purpose. The purpose of this study was to investigate the relationship between body image, self-esteem, and family strengths in female university students. Methods. One hundred ninety nine female university students participated in data collection. Data on body image, self-esteem, and family strengths were collected via questionnaire between April 2013 and May 2013. Data analysis was done using PASW 18.0 program and included one-way ANOVA, independent t-test and Pearson correlation coefficients analysis. Results. The mean score of body image was 24.20, self-esteem was 25.30, and family strengths was 83.71. Results showed a positive correlation among body image and self-esteem(r=.19, p<.001), and family strengths(r=.16, p<.001). Conclusion. The results indicate that it is necessary to increase body image, self-esteem, and family strengths among female university students. To ensure resonable body image in female university students, self-esteem, and family strengths should be reinforced.

Purpose: The purpose of this study was to identify the levels of body image, sexual intimacy, and sexual satisfaction, and to explore factors affecting sexual intimacy and satisfaction among women within one year of mastectomy. Methods: The present study was a cross-sectional survey and involved 101 women who had undergone mastectomy at a University hospital of D city, Korea. Measurement included the scales of body image, sexual intimacy, and sexual satisfaction. Results: Mean age of the subjects was 51 years. Scores of the body image, sexual intimacy, and sexual satisfaction were 59.62, 90.69, and 69.04, respectively. Body image, sexual intimacy, and sexual satisfaction were significantly related to each other. Sexual intimacy was higher when women were of young age (${\beta}=-.32$), had a shorter period since surgery (${\beta}=-.24$), and with higher levels of body image (${\beta}=.37$). Sexual satisfaction was higher when women had higher levels of body image (${\beta}=.19$) and greater levels of sexual intimacy (${\beta}=.74$). Conclusion: Higher levels of body image and greater levels of sexual intimacy were identified as the significant factors influencing sexual satisfaction among these women. Future research with a mixed-method research is needed to gain a deep understanding of the sexuality between women and their husbands.

This study aims to determine the association between obesity-related behaviors (dietary practices, physical activity and body image) and body weight status among adolescents. A total of 382 adolescents (187 males and 195 females) aged 13 to 15 years in Kajang, Selangor participated in this study. Majority of the respondents were Malays (56.0%), followed by Chinese (30.1%) and Indians (13.9%). Dietary practices, physical activity and body image of the adolescents were assessed through the eating behaviors questionnaire, two-day dietary record, two-day physical activity record and multi-dimensional body image scale (MBIS), respectively. Body weight and height were measured by trained researchers. The prevalence of overweight and obesity (19.5%) was about twice the prevalence of underweight (10.5%). About two-thirds of the respondents (72.3%) skipped at least one meal and half of them (56.2%) snacked between meals with a mean energy intake of $1,641{\pm}452$ kcal/day. More than half of the respondents (56.8%) were practicing sedentary lifestyle with a mean energy expenditure of $1,631{\pm}573$ kcal per day. Energy intake (r = 0.153, P < 0.05), physical activity (r = 0.463, P < 0.01) and body image (r = 0.424, P < 0.01) were correlated with BMI. However, meal skipping, snacking and energy expenditure per kg body weight were not associated with body weight status. Multiple linear regression analysis showed that body image, physical activity and energy intake contributed significantly in explaining body weight status of the adolescents. In short, overweight and obesity were likely to be associated not only with energy intake and physical activity, but also body image. Hence, promoting healthy eating, active lifestyle and positive body image should be incorporated in future obesity prevention programmes in adolescents.

The objective of this study was to verify the effects of brand equity of small & medium hospitals on trust and relationship commitment and mediation effect of trust in the relation between brand equity and relationship commitment. For testing reliability and validity of the measurement tool, Cronbach's ${\alpha}$ and confirmatory factor analysis was used, respectively. A structural equation model was applied for verifying the study model suggested. Out of 450 questionnaires distributed, 439 was returned. On the study results, brand image and perceived quality positively determined trust of customers for small & medium hospitals. Customers' trust also has a positive effect on relationship commitment. Brand awareness positively influence the levels of relationship commitment. Moreover, a mediation effect was identified. Customers' trust mediated the effects of brand image and perceived quality on relationship commitment of hospitals customers. On conclusions, relationship commitment was determined, either directly or indirectly, by brand image and perceived quality, while trust mediated the their relationship. Thus, hospitals management may use the concepts of brand equity and trust as a key success factor of their business purposes.

Colonoscopy plays an important role in reducing the incidence and mortality of colorectal cancer by detecting adenomas and other precancerous lesions. Image-enhanced endoscopy (IEE) increases lesion visibility by enhancing the microstructure, blood vessels, and mucosal surface color, resulting in the detection of colorectal lesions. In recent years, various IEE techniques have been used in clinical practice, each with its unique characteristics. Numerous studies have reported the effectiveness of IEE in the detection of colorectal lesions. IEEs can be divided into two broad categories according to the nature of the image: images constructed using narrow-band wavelength light, such as narrow-band imaging and blue laser imaging/blue light imaging, or color images based on white light, such as linked color imaging, texture and color enhancement imaging, and i-scan. Conversely, artificial intelligence (AI) systems, such as computer-aided diagnosis systems, have recently been developed to assist endoscopists in detecting colorectal lesions during colonoscopy. To gain a better understanding of the features of each IEE, this review presents the effectiveness of each type of IEE and their combination with AI for colorectal lesion detection by referencing the latest research data.
