  • Objective: To establish diagnostic criteria for pulmonary arterial hypertension (PAH) in children by using parameters obtained through noninvasive cardiac computed tomography (CCT). Materials and Methods: We retrospectively measured parameters from CCT images of children from a single institution in a multiple stepwise process. A total of 208 children with mean age of 10.5 years (range: 4 days-18.9 years) were assessed. The variables were classified into three groups: the great arteries; the ventricular walls; and the bilateral ventricular cavities. The relationship between the parameters obtained from the CCT images and mean pulmonary arterial pressure (mPAP) was tested and adjusted by the children's body size. Reference curves for the pulmonary trunk diameter (PTD) and ratio of diameter of pulmonary trunk to ascending aorta (rPTAo) of children with CCT images of normal hearts, adjusted for height, were plotted. Threshold lines were established on the reference curves. Results: PTD and rPTAo on the CCT images were significantly positively correlated with mPAP (r > 0.85, p < 0.01). Height was the body size parameter most correlated with PTD (r = 0.91, p < 0.01) and rPTAo (r = -0.69, p < 0.01). On the basis of the threshold lines on the reference curves, PTD and rPTAo both showed 88.9% sensitivity for PAH diagnosis, with negative predictive values of 93.3% and 92.9%, respectively. Conclusion: PTD and rPTAo measured from CCT images were significantly correlated with mPAP in children. Reference curves and the formula of PTD and rPTAo adjusted for height could be practical for diagnosing PAH in children.

  • According to most experts and health workers, a living creature's body heat is little understood and crucial in the identification of disorders. Doctors in ancient medicine used wet mud or slurry clay to heal patients. When either of these progressed throughout the body, the area that dried up first was called the infected part. Today, thermal cameras that generate images with electromagnetic frequencies can be used to accomplish this. Thermography can detect swelling and clot areas that predict cancer without the need for harmful radiation and irritational touch. It has a significant benefit in medical testing because it can be utilized before any observable symptoms appear. In this work, machine learning (ML) is defined as statistical approaches that enable software systems to learn from data without having to be explicitly coded. By taking note of these heat scans of breasts and pinpointing suspected places where a doctor needs to conduct additional investigation, ML can assist in this endeavor. Thermal imaging is a more cost-effective alternative to other approaches that require specialized equipment, allowing machines to deliver a more convenient and effective approach to doctors.

  • The purpose of this study is to investigate the effect of body type(thin, standard, fat), necktie width(narrow, medium, wide), gender(man, woman) on image formation. Sets of stimulus and response scales(7 point semantic) were used as experimental materials. The stimuli were 9 color pictures manipulated with the combination of necktie-width and body type using computer simulation. The subjects were 116 male undergraduates and 99 female undergraduates living in Gyeongsangnam-do. Image factor of the stimulus was composed of 4 different components, young-activity, attractiveness-gracefulness, stability, and boldness. In the young-activity, attractiveness-gracefulness and stability, body type and necktie-width showed independent effect. In the boldness, body type showed independent effect. Significant interaction effects of body type and necktie-width on young-activity, attractiveness-gracefulness and stability were found. For young-activity image, necktie of narrow width were effective. For attractiveness-gracefulness image, body type of standard were effective. For stability image, body type of standard and body type of thin on necktie of narrow and medium width were effective. The male fashion image can be perceived differently according to combination of the clues used in body type and necktie-width. Therefore, when the male fashion to create images that will have to consider the body type and necktie width.

  • This article is to understand the implications and ideological meaning of female normative beauty reproduced by the idealizing phenomena of the hyper-real body as a process of the normalization of the body projected in fashion magazines with a focus on the body created by the increased influence of mass media in consumer capitalism. This study conducts a literature research and semiotic analysis as the method of investigation and focuses on the body images of the beauty articles in Vogue Korea. The idealizing phenomena of the hyper-real body in fashion magazines emphasizes that the body is an exchangeable substance that can be disassembled to adjust to accord with the standards and norms of society, that the ability of individuals to manage their body is enhanced by a rise in social class, and concludes that the superficial alteration of the body image is related to the standard of a moral tendency where a young and slender figure is considered to be a well managed body image.

  • In this paper, we propose a technique for automatic spinal deformity detection from $moir\acute{e}$ topographic images. Normally the $moir\acute{e}$ stripes show symmetry as a human body is almost symmetric. According to the progress of the deformity of a spine, asymmetry becomes larger. Numerical representation of the degree of asymmetry is therefore useful in evaluating the deformity. First, displacement of local centroids and difference of gray values are evaluated statistically between the left- and the right-hand side regions of the $moir\acute{e}$ images with respect to the extracted middle line. We classify the moire images into two categories i.e., normal and abnormal cases from the features, employing discriminant analysis. An experiment was performed employing 1,200 $moir\acute{e}$ images and 85% of the images were classified correctly.

  • One of the most significant feature of diagnostic ultrasonic instrument is to display information on the soft tissues in the body in real time. In this paper we carried out basic study on the digital moving image processing for tracing the movement of heart valves in echocardiograms. Digital moving image file was made from analog echocardiograms and it was remade as 256 gray-level images on each frame. The ROI(Region of interest) was placed on a heart valve region to process images efficiently. Images were processed by the use of image enhancement filters and morphology filters. The result shows that the processed images were more enhanced than original images. When a moving image is reconstructed by using these enhanced images, we can trace the movement of heart valves more easily. In this study we proposed the availability of the moving image reconstruction using enhancement images.

  • The purpose of this study was to investigate the Avant-garde's aesthetic values and expressoinal characteristic, and to find out(analysis) the design characteristic of Avant garde fashion since 1995. Expressoinal characteristics of Avant garde with the anti-aesthetic, radically pursuing newness, and open mind, are revealed dynamism, hostile innovation, and experimentalism. Futuristic images expressed in dynamism represent space style, body conscious style, cyborg style, kinetic style, and primitive style. And deconstructional images related to hostile innovation show punk style, grunge style, humor style, and abstractive style. Also surreal images related to experimentalism hold erotic style, depasemant style, deformation style, and collage style. The proper usage of newness offers the escape, the vividness, and the humour from the fatigue of the life and so, it is expected to offer the chance of transfering the active individuals and societies directly or indirectly By analyzing the instances for the images of avant-garde fashion since 1995, the contribution about the expectation of the design trends of the present and future is expected.
