In this paper, we propose an adult images detection algorithm using a mean intensity filter and an improved 2D Hough Transform. This paper is composed of three major steps including a training step, a recognition step, and a verification step. The training step generates a mean nipple variance filter that will be used for detecting nipple candidate regions in the recognition step. To make the mean variance filter, we converts an input color image into a gray scale image and normalize it, and make an average intensity filter for nipple areas. The recognition step first extracts edge images and finds connected components, and decides nipple candidate regions by considering the ratio of width and height of a connected component. It then decides final nipple candidates by calculating the similarity between the learned nipple average intensity filter and the nipple candidate areas. Also, it detects breast lines of an input image through the improved 2D Hough transform. The verification step detects breast areas and identifies adult images by considering the relations between nipple candidate regions and locations of breast lines.

This study analyzed the portrayal of adult characters in 176 picture books published in Korea by variables of character's external condition(sex, name, age and occupation), type(3-dimensional or flat), conflicts, and image. Standards for analysis of the picture books were devised by the researcher. Results showed that (1) adult male characters appeared much more frequently than female; they appeared most often without names and in order of older, middle aged, young adult. They appeared most often without occupations. (2) 3-dimensional characters appeared much more than flat ones. (3) Adult conflict situations were rare and were mostly interpersonal. They often resolved their conflicts by themselves. (4) The 20 kinds of images of the adult characters were mostly humorous, warm-hearted and attentive.

We aims to perform comparative analysis on the dose area and image qualities varying on the slice thickness when using Automatic Exposure Controller (AEC) and manual exposure; thus, it wants to suggest a measure to reduce exposure dose by setting the optimal examination condition for each slice thickness. The method was to set the thickness as Thin, Normal, and Heavy adult and evaluate the dose area, spatial resolution, low contrast resolution, Signal to Noise Ratio (SNR) and Contrast to Noise Ratio (CNR) according to each slice thickness by using the AEC and the manual exposure controller. The dose area according to each slice thickness all increased both when using the AEC and the manual exposure. However, the manual exposure showed lower dose area product than the AEC. Spatial resolutions and low contrast resolutions were all observed to be higher than the evaluation standard. Also, the SNR and CNR of each thickness all increased when using the AEC. When using the manual exposure, SNR and CNR increased in all cases other than the Heavy Adult. Consequently, the Thin and Normal Adult showed dose reduction about 2 times when using the manual exposure controller, while ensuring the image quality. Heavy adult was able to maintain good image quality by using AEC.

Purpose: The purpose of this study was to describe the degrees of body image, self esteem and Health Related Quality Of Life (HRQOL), and to identify factors related to these variables in patients with Crohn's disease. Methods: A descriptive cross sectional survey design was used. The 148 participants were the patients with Crohn's disease, recruited conveniently from one metropolitan hospital located in Seoul, Korea. The collected data were analyzed with SPSS/WIN program. Results: Patients with severe illness activity reported significantly lower body images than those of the others. Education levels and working states affected self-esteem positively, while the number of operations and illness activity affected self-esteem negatively. Hospitalization and illness activity affected HRQOL negatively. Body image, self esteem, and HRQOL were positively correlated to each other with statistical significance. Illness activity was a common factor to affect body image, self esteem, and HRQOL. Body image was an influential factor on HRQOL as well as illness activity in patients with Crohn's disease. Conclusion: As a result, this study suggested a necessity for developing an intervention study to lower the illness activity and heighten the body image among the patients with Crohn's disease.

Purpose: The purpose of this study was to investigate the influences of body mass index (BMI), mindfulness and self-esteem on reported body image among university students. Methods: Data were collected through questionnaires from 266 students and were analyzed using descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficients and Stepwise multiple regression analysis with SPSS/WIN 19.0 program. Results: As defined by body mass index, the sample was divided into an underweight group was 88.7%, a normal weight group was 10.5%, and an overweight group was 0.8%. The levels of body image depended on family income, personality, and BMI. The body image was significantly correlated with BMI, mindfulness, and self-esteem. The influential factors affecting body image were self-esteem, BMI, family income and personality, which explained about 34.6% of the variance. Conclusion: The results of this study indicate that nursing intervention are needed to improve body image, and that such variables should be carefully considered in intervention for university students.

The main issue of CT is radiation dose reduction to patient. The purpose of this study was to estimate the image quality and dose by iterative reconstruction (IR) for adults and pediatrics. Adult and pediatric images of phantom were obtained with 120 and 140 kV, respectively, in accordance with radiation dose in terms of volume CT dose index ($CTDI_{vol}$): 10, 15, 20, 25, 30, 35 mGy. Then, the adult and the pediatric images are reconstructed by filtered-backprojection (FBP) and iterative reconstruction (IR). The images were analyzed by signal-to-noise ratio (SNR). SNR is improved when IR and 140 kV are applied to acquire adult and pediatric images. In the adult abdomen, according to diagnostic reference level, the SNR values of bone were increased about 27.84 % and 27.77 % at 120 kV and 140 kV, and the tissue's SNR values of the IR were increased about 29.84 % and 33.46 % 120 and 140 kV, respectively. Dose is reduced to 40% in adults abdomen images when using IR reconstruction. In pediatric images, the bone's SNR were also increased about 17.70% and 18.17 % at 120 kV and 140 kV. The tissue's SNR were increased about 26.73 % and 26.15 % at 120 kV and 140 kV. Radiation dose is reduced from 30% to 50% for bone and tissue images. In the case of examinations for adult and pediatric CT, IR technique reduces radiation dose to patient, and it could be applied to adult and pediatric imaging.

This study investigated the relationships between eating disorder risk, body image perception, weight control, and dietary habits in Korean women. Body shape perception, the Eating Attitude Test (EAT-26) and dietary habit information were collected by a self-administered questionnaire to 373 adult women and the data were analyzed by the Chi-square test. 31.4% of the women were classified in the eating disorder group by a score of over 20 points on the EAT-26. Compared to the normal group, more women in the eating disorder risk group perceived that a thin body shape was the ideal body shape and were dissatisfied with their body shape. This group was also more interested in weight control and more likely to try weight control methods. The eating disorder risk group was more likely to skip meals and snacks than the normal group. In addition, they had a greater appetite and a higher frequency of overeating than the normal group. Over 30% of the Korean women surveyed were categorized at high risk of eating disorders. They were more likely to overestimate body weight and shape and tried to control their weight by inappropriate methods. To prevent eating disorders in adult women, nutrition education programs should incorporate strategies to change inaccurate self-body image and to disseminate information about healthy weight control methods.
