Due to the development of the media, the digital image is gradually developed, giving some motion to the still image called Cinemagraphs, thereby enhancing the visual perceptional ventilation. In today's advertising media, visual stimuli are transmitted through Cinemagraphs. Demonstrate what is conveyed by aesthetics through case studies and experimental studies. In addition, through Cinemagraphs, the possibility of aesthetic technique is confirmed, and the features of Cinemagraphs will become a new trend in the field of design studying digital images. As IT technology becomes increasingly sophisticated and easy to make, it is expressed as a cultural symbolic pleasure of the masses. The value of future research will be significant.

Using semiotic analysis, visual images in selected postmodern fashion advertisements were analyzed. Semiotics is the study of the structure of the meanings of signs. Semiotic analysis involves deconstruction, and thus draws on the researcher’s value-mediated introspection and subjective interpretation of texts i.e., ads). Through deconstruction, culturally assigned meanings, which represent consumers and culture, were revealed. Postmodern characteristics including open interpretation, use of the human body as an object, multi page format, new mood, black and white scenes, use of real people, and new ideology were identified in the ads. The importance of analyzing visual images in fashion ads was stressed in the findings of the study, as was the importance of educating consumers on how to read the visual images.

In a situation where the demand for creative talent creating new values and ideas is increasing day by day in the 21st century, students dealing with technology in the IT field have quite insufficient communication skills of materializing ideas and logically visualizing them. Therefore, the importance of systematic means of expression and methodology that can convey ideas more effectively and sensitively in the IT field is increasing. In this study, we recognized the importance of idea visualization education in the IT field by reviewing the relevant theory and examining creative thinking system cases and sought a more systematic visual communication method by investigating the awareness on creative thinking and expression. The results obtained in this study are considered to not only provide academic value as basic research in building new education programs in the IT sector in the future but be an opportunity for further research associated with creative talent training.

The autonomous underwater vehicle (AUV) is being widely researched in order to achieve superior performance when working in hazardous environments. This research focuses on using image processing techniques to estimate the AUV's egomotion and the changes in orientation, based on image frames from different time frames captured from a single high-definition web camera attached to the bottom of the AUV. A visual odometry application is integrated with other sensors. An internal measurement unit (IMU) sensor is used to determine a correct set of answers corresponding to a homography motion equation. A pressure sensor is used to resolve image scale ambiguity. Uncertainty estimation is computed to correct drift that occurs in the system by using a Jacobian method, singular value decomposition, and backward and forward error propagation.

The visual discrimination ability of Vespertilio superans was investigated with a male and a female. In a controlled experimental situation (two-choice apparatus), using a vertical bar and a circle of the same area of the bar, it was established that discrimination between different shapes of the same size was impossible. However, with patterns in which the surface areas substantially differed, the bats were able to discriminate between them to a statistically significant degree. Continuing with experiments in which the lightness of the 2 paritems was varied, the disrimination was possible with all but the slightest differences in lightness (a difference of lightness value 2).

Substitution of graphic representation for extensive lists of numerical statistical data is highly desirable by both editors and readers of medical journals, faced with an exploding abundance of contemporary medical literature. A novel graphic tool. the 'double-ring diagram', is described herein which permits visual representation of information regarding certain statistical variables used to describe the performance of a test or physical sign in the diagnosis of a disease. The diagram is relatively easy to construct on the basis of a number of primary data such as the prevalence and the true positive, true negative. false positive and false negative test results. These values are reflected in the diagram along with the values of other statistical variables derived from them. such as the sensitivity. specificity, predictive values for positive and negative test result. and accuracy. This diagram may be useful in visualizing a test's performance and facilitating visual comparison of performance of two or more tests.

This study analyzes whether a person's visual perception differs according to the kinds of light source. Evaluations of the effects of space, color-tone and texture perception revealed that different kinds of light sources change the perception of finishing material. The perception from directly attached lamps was compared to an environment with both directly attached lamps and supplemental lighting. We found the perception changed with changes in the types of supplemental light source We compared the mean value of each perception and found that perceptions change most when incandescent lights were followed by halogen. Thus, one should account for the changes in perception that occur as a result of these changes.

In recent years, the Guochao style of virtual idols has proliferated, and the virtual idol market in China has witnessed gradual growth. As Guochao combines traditional Chinese culture with modern aesthetics, it shapes a distinctive visual identity for Chinese virtual idols. We address the current research gap by exploring the characteristics of Guochao style in virtual idol design through literature analysis, semiotics, and comparative studies. We examine how Guochao virtual idols represent the convergence of Chinese culture and modern technology, reflecting cultural characteristics of the era. Through our analysis of virtual idol design, we identify key design features of Guochao virtual idols, bridging a theoretical void in this area. We propose recommendations to foster a more dynamic and culturally enriched virtual idol industry in China. Our research provides new insights into integrating Guochao elements into virtual idol design as an approach to differentiate amid competition while promoting traditional Chinese culture through digital media. We demonstrate how this design approach enhances the uniqueness and cultural value of Chinese virtual idols, contributing to the field's theoretical foundation and practical applications.

This study was conducted to analyze the Korean inclination to visual equivocality. Similar studies conducted by several psychologists were reviewed in order to determine whether we can put equal value on the visual equivocality which is often shown in natural appearance. This Korean inclination was also investigated with the help of a public survey. The following conclusions were derived from the study. - In reality, there is no visual equivocality for Koreans except in some specific cases. - It is true that, on a screen, a diagonal line from the lower right to the upper left produces a stronger feeling of upward tendency than one from the lower left to the upper right. - The idea that the right side of a screen looks heavier than the left one was not supported and should be rejected for Koreans. - It was discovered that the user interface is working when a person is describing a natural appearance or looking at a description. This fact is generally accepted for Koreans, the majority of whom are right-handed. - Until now, the idea of a Korean superiority toward the left side in visual expression has been found in our culture. In short, it was uncovered that Korean people generally do not have visual equivocality but, instead, have an inclination to left side rather than the right from various aspects.

The purposes of this study were to examine the normal lumbar proprioception and identify the effect of vision and proprioception on lumbar movement accuracy through measuring a reposition error in visual and non-visual conditions and to provide the basic data for use of vision when rehabilitation program is applied. The subjects of this study were 39 healthy university students who have average physical activity level. They were measured the ability to reproduce the target position(50% of maximal range of motion) of flexion, extension, dominant and non-dominant side flexion in visual and non-visual conditions. Movement accuracy was assessed by reposition error(differences between intended and actual positions) that is calculated by the average of absolute value of 3 repeated measures at each directions. The data were analysed by paired samples t-test, independent samples t-test, and repeated measures ANOVA. The results were as follows : 1. Movement accuracy of flexion, extension, dominant side flexion, and non-dominant side flexion was increased in visual condition. 2. There were no differences in the lumbar movement accuracy between sexes in visual and non-visual conditions. 3. In non-visual condition, the movement in coronal plane(dominant and non dominant side flexion) is more accurate than that in sagittal plane(flexion and extension). 4. In non-visual condition, there were no differences in the lumbar movement accuracy between dominant and non-dominant side flexion. In conclusion, this study demonstrates that the movement is more accurate when the visual information input is available than proprioception is only available. When proprioception is decreased by injury or disease, it disturbs the control of posture and movement. In this case, human controls the posture and movement by using visual compensation. However it is impossible to prevent an injury or trauma because most of injuries occur in an unexpected situation. For this reason, it is important to improve the proprioception. Therefore, proprioceptive training or exercise which improve the ability to control of posture and movement is performed an appropriate control of permission or interception of the visual information input to prevent an excessive visual compensation.
