Background: Many studies have pointed to strategies to cope with patient anxiety in colposcopy. Evidence shows that patients experienced considerable distress with the large loop excision of transformation zone (LLETZ) procedure and suitable interventions should be introduced to reduce anxiety. This study aimed to investigate the effects of music therapy in patients undergoing LLETZ. Materials and Methods: A randomized controlled trial was conducted with patients undergoing LLETZ performed under local anesthesia in an out patient setting at Ramathibodi Hospital, Bangkok, Thailand, from February 2015 to January 2016. After informed consent and demographic data were obtained, we assessed the anxiety level using State Anxiety Inventory pre and post procedures. Music group patients listened to classical songs through headphones, while the control group received the standard care. Pain score was evaluated with a visual analog scale (VAS). Statistical analysis was conducted using Pearson Chi-square, Fisher's Exact test and T-Test and p-values less than 0.05 were considered statistically significant. Results: A total of 73 patients were enrolled and randomized, resulting in 36 women in the music group and 37 women in the non-music control group. The preoperative mean anxiety score was higher in the music group (46.8 VS 45.8 points). The postoperative mean anxiety scores in the music and the non-music groups were 38.7 and 41.3 points, respectively. VAS was lower in music group (2.55 VS 3.33). The percent change of anxiety was greater in the music group, although there was no significant difference between two groups. Conclusions: Music therapy did not significantly reduce anxiety in patients undergoing the LLETZ procedure. However, different interventions should be developed to ease the patients' apprehension during this procedure.

This article analysis the aesthetics of metal-body of (1989) and its metamorphosis of dehumanization through visual desires expressed by body images. This paper suggests theoretical analysis based on aesthetic views to understand the underlying meanings. The research categorizes three types of images; surreal image, grotesque image and eros image from the metamorphosis of dehumanization and transformation throughout the film. As the surreal image, the metamorphic process of transformation, demolition, derangement, illusion, and human desire continues to reflect the evil side of a human in everyday life. It also visualizes the images of exaggeration through weakness and bizarre side of metal-body. The grotesque image of body metamorphosis displays and symbolizes double-sides of bizarre and weak side of human in the everyday environment when malformation reaches its peak when Tetsuo finally shows his transforming figure. Finally, the eros image is analogized as a man's inner self and self-destruction in surreal world and a grotesque figure when overwhelming desire of transforming into rebirth of a perfect metal-body, Tetsuo. The surreal image, grotesque image, and eros image portraits human desires inner and outer-self into visualized image and that represents the means of excessive desire for dreaming of world domination with merging non-organic medium of metal and organic body to create a perfect body-image.

Recently, The wide range of the Internet applications and the related technology developments enabled the ease use of the digital multimedia contents (fixed images, movies, digital audios). However, due to the replay ability which the contents may be easily duplicated and not only the duplicates are capable of providing the same original quality. There are mainly the encipher techniques and the watermarking techniques which are studied and used as solutions for the above problem in order to protect the license holders' rights. To the protection of the IP(Intellectual Property) rights of the owner, digital watermarking is the technique that authenticates the legal copyrighter. This paper proposed the watermarking algorithms to watermark the 256 gray logo image and the color image by applying the wavelet transformation to the color stand-still images. The proposed algorithms conducted the watermark insertion at the LH frequency region among the wavelet transformation regions (LL, LH, HL, HH). The interleaving algorithms which applied in data communication was applied to the watermark. the amount of watermark increased which consequently caused the PSNR to decrease but this might provide the perseverance against the external attacks such as extraction, filtering, and crop.

This study, which was begun in order to create a metal molding by using lines, a basic element of design, examined various characteristics and concept of line and the beauty of lines based on previous research on the subject. The result showed that formative interpretation of lines largely depends on intentional expression by using thickness and rhythm of lines. In order to obtain a metal molding that provides both visual freedom and beauty, rather than the conventional formative expression of lines, I used red copper plate and Phosphor bronze line for creating a pattern based on transformation and repetition of lines and an artwork based on the pattern. The result was not only a creation of a plane but the senses of three-dimension, speed, and unity in the overall shape. Further research will need to be conducted regarding formative interpretation of lines and emotional and intrinsic beauty through expression of lines.

In this paper, we propose colored-hear recognition that distinguishing feature of synesthesia for human sensing by shared vision and specific sense of hearing. We perceived what potential influence of human's structured object recognition by visual analysis through the camera, So we've studied how to make blind persons can feel similar vision of real object. First of all, object boundaries are detected in the image data representing a specific scene. Then, four specific features such as object location in the image focus, feeling of average color, distance information of each object, and object area are extracted from picture. Finally, mapping these features to the audition factors. The audition factors are used to recognize vision for blind persons. Proposed colored-hear transformation for recognition can get fast and detail perception, and can be transmit information for sense at the same time. Thus, we were get a food result when applied this concepts to blind person's case of image recognition.

In this paper, a texture feature extraction method using local energy and local correlation of Gabor transformed images is proposed and applied to an image retrieval system. The Gabor wavelet is known to be similar to the response of the human visual system. The outputs of the Gabor transformation are robust to variants of object size and illumination. Due to such advantages, it has been actively studied in various fields such as image retrieval, classification, analysis, etc. In this paper, in order to fully exploit the superior aspects of Gabor wavelet, local energy and local correlation features are extracted from Gabor transformed images and then applied to an image retrieval system. Some experiments are conducted to compare the performance of the proposed method with those of the conventional Gabor method and the popular rotation-invariant uniform local binary pattern (RULBP) method in terms of precision vs recall. The Mahalanobis distance is used to measure the similarity between a query image and a database (DB) image. Experimental results for Corel DB and VisTex DB show that the proposed method is superior to the conventional Gabor method. The proposed method also yields precision and recall 6.58% and 3.66% higher on average in Corel DB, respectively, and 4.87% and 3.37% higher on average in VisTex DB, respectively, than the popular RULBP method.

Depaysement, suggested by the well-known surrealist Rene Magritte, has been used for and applied to many media. Application of depaysement through various media such as TV, commercial, and advertisement, attempted to provide interest by deviation from fixed ideas and visual shock, placing common objects in new and strange environment. The study applied screen projection mapping using a transparent screen and objet for different purposes to projection mapping media, applying depaysement to the artwork 'Illusion' in order to suggest visual pleasure, possibility as a new media, and projection mapping using transparent screen and objet. The work cases were suggested by applying expressive methods and effects according to three classifications - modulation of space, combination of conflicting images, and transformation and change of objects - in depaysement, and analyzed by types based on classification of the layout, typography, image, color, and time. Through 'Illusion,' new objet and characteristics of the media are applied and expanded by using projection mapping and depaysement.

Projector-based visual systems are widely used for VR and experience display applications. But the illumination irregularity on the screen surface due to the screen material and its light reflection properties sometimes deteriorates the user experience. This phenomenon is particularly troublesome when the participants of the head tracking VR system such as CAVE or the motion generation experience system continually move around the system. One of reason to illumination irregularity is projector-screen specular reflection component to participant's eye's position and it's analysis needs high computation complexity. Similar to calculate specular lighting term using GPU's programmable shader, Our research adjusts every pixel's brightness in runtime with given 3D screen space model to reduce illumination irregularity. For doing that, Angle-based brightness compensate function are considered for specific screen installation and modified it for GPU-friendly compute and access. Two aspects are implemented, One is function access transformation from angular form to product and the other is piecewise linear interpolate approximation.

The material world around human is normally composed of opaque one, with which human has made the spaces. The opaque material to make space has played a role to control the relationship among people and has produced socio-cultural things since the history started. The opening of opaque material(wall) connects one space with the other. Therefore, the meaning of opening is a connection among people who are in different spaces in terms of sociology. In conjunction with this, socio-cultural situation has been deployed differently. In the traditional european domestic space, the glass has been applied to this opening since they found the glass. It disconnects two spaces physically but connects them visually. Therefore, without blocking the opening visually, the glass became to protect people with their interior space from outside environment. The important thing is that the application of the glass in a building had been restricted because of opening size. However, after Industrial Revolution with the advanced technology of architecture, the glass came to be applied to the building and it became widen. So, the concept of glass window became to be the one of glass wall. This change made a transformation of visual character between two spaces which are separated with glass wall. This means that the glass wall gave two directional visibility while the glass window gave one directional visibility from inside to outside of space. This is because the amount of the natural light to the interior space increased due to widen glass in a space. This gave a change of visual authority and the space of surveillance(interior space) became to the one of communication. The space of surveillance, Michel Foucault mentioned in his book surveillance and punishment, is a very private one that is not visually permeable from the people outside, while the space of communication is a public one which needs other eyes. In the space of publicity, there needs a rationality, morality and ethics because of public surveillance and in the space of privacy, there restores a desire for sex and assaults.

This study attempts to create an analytical framework of the transformation and transmission of knowledge by teachers to students. I focuses on the assertion that the cognitive thinking of a teacher is reflected in his use of mathematical language. Mathematical language is one of the critical elements of communicating mathematical knowledge to students. I examined the cognitive teaching style of different teachers as expressed in their use of mathematical language. An analytical framework of Mathematics Teaching styles was created integrating thinking factors of each visual and analytic style into 5 categories. After that, I regarding the teaching style of mathmatics teachers places its significance not on which teaching style is right or wrong but on identifying the strong and weak points of the teaching styles through actual analysis. With the help of this analytical framework, I conducted an analysis on the videotaped classes and found that the teachers were not biased to one side but in fact there were teachers who demonstrated visual, analytic or mixed teaching style. Therefore, I concludes that math teachers can analyze their teaching styles and improve them through the analytical framework provided in these findings.
