This paper aimed to investigate the difference of clothing behavior and desired image according to individualism-collectivism cultural tendency for women. A survey of 217 adult women was conducted from November to December 2006, mainly in Daegu. Reliability, frequency, percentage, factor analysis, ANOVA, t-test, Tukey test and an -analysis were used for data analysis by using SPSS WIN 11.0 package. The results were as follows: First, while the group with a higher tendency toward individualism valued personality and convenience above everything else, the group which has a higher tendency to collectivism disposition has a much greater interested in conformity and brand-orientation. Second, while the group with a higher tendency toward individualism pursued an bold image for their clothing, the group with a higher tendency toward collectivism preferred a feminine and plain image. Third, regarding the individualism-collectivism and demographic peculiarity, there were no significant differences between the two groups according to marital status and average monthly income. However, there were significant differences in individualism-collectivism among the groups determined by age, occupation, educational background and rural or urban background.

This study was conducted to find adolescent females perception of body image. The survey was carried out by self-questionnaires with 463 female school and college students in Daegu. Analysis of data was done using t-test, and ANOVA with the SAS computer program. The average height, weight and BMI of the subjects were 161.2cm, 53.4kg and 20.51kg/$m^2$. It appeared that 33.3% of the subjects were off the normal range of body weight ; in particular 25.1% of the subjects were under weight. While the subjects’perception of their own current body image was not distorted, they were dissatisfied with their body image because they wanted a very thin figure. Subjects were divided into 3 groups -underweight, normal weight, overweight-according to their current body size. Their perceptions of ideal and desired figures differed significantly between the groups, but they thought a thinner figure than normal body image as ideal and desired body image even in overweight group. As a result, dissatisfaction of body image in the overweight group was significantly larger than the normal-weight group, and that of the normal-weight group was larger than the underweight group. Percentages of weight control attempt were 51.7% and 64.7% in the normal weight and underweight subjects, respectively. Subjects were divided into 2 groups according to their weight control experience : those who have attempted, and who have not attempted. Weight control attemptees had a higher level of dissatisfaction with their body image than non-attemptees, both because weight control attemptees were fatter, and they perceived a thinner figure as an ideal and as a desired body image thin non-attemptees. From the results of this study, we confirmed that one of reasons of excessive weight control behavior among adolescent females was distorted perception about ideal body image.

Visual servoing is the fusion of results from many elemental areas including high-speed image processing, kinematics, dynamics, control theory, and real-time computing. It has much in common with research into active vision and structure from motion, but is quite different from the often described use of vision in hierarchical task-level robot control systems. We present a new approach to visual feedback control using image-based visual servoing with the stereo vision in this paper. In order to control the position and orientation of a robot with respect to an object, a new technique is proposed using a binocular stereo vision. The stereo vision enables us to calculate an exact image Jacobian not only at around a desired location but also at the other locations. The suggested technique can guide a robot manipulator to the desired location without giving such priori knowledge as the relative distance to the desired location or the model of an object even if the initial positioning error is large. This paper describes a model of stereo vision and how to generate feedback commands. The performance of the proposed visual servoing system is illustrated by the simulation and experimental results and compared with the case of conventional method for dual-arm robot made in Samsung Electronics Co., Ltd.

Visual place recognition is widely researched area in robotics, as it is one of the elemental requirements for autonomous navigation, simultaneous localization and mapping for mobile robots. However, place recognition in changing environment is a challenging problem since a same place look different according to the time, weather, and seasons. This paper presents a feature extraction method using a deep convolutional auto-encoder to recognize places under severe appearance changes. Given database and query image sequences from different environments, the convolutional auto-encoder is trained to predict the images of the desired environment. The training process is performed by minimizing the loss function between the predicted image and the desired image. After finishing the training process, the encoding part of the structure transforms an input image to a low dimensional latent representation, and it can be used as a condition-invariant feature for recognizing places in changing environment. Experiments were conducted to prove the effective of the proposed method, and the results showed that our method outperformed than existing methods.

In teleoperating, as seeing the monitor screen obtained from a camera instituted in the working environment, human operator generally controls the slave arm. Because we can see only 2-D image in a monitor, human operator does not know the depth information and can not work with high accuracy. In this paper, we proposed a traded control method using an visual sensor for the purpose of solving this problem. We can control a teleoperation system with precision when we use the proposed algorithm. Not only a human operator command but also an autonomous visual sensor feedback command is given to a slave arm for the purpose of coincidence current image features and target image features. When the slave arm place in a distant place from the target position, human operator can know very well the difference between the desired image features and the current image features, but calculated visual sensor command have big errors. And when the slave arm is near the target position, the state of affairs is changed conversely. With this visual sensor feedback, human does not need coincide the detail difference between the desired image features and the current image features and proposed method can work with higher accuracy than other method without, sensor feedback. The effectiveness of the proposed control method is verified through series of experiments.

The purpose of this study is to extract the factors that compose the image of science teacher desired by elementary school students in inquiry-based instruction and analyze the structural associations between them. Factors that compose the image of science teacher desired by elementary school students in inquiry-based instruction were extracted through exploratory factor analysis (EFA). Based on the findings of EFA, the questionnaire has been further analyzed using confirmatory factor analysis (CFA). In addition, based on the factor structure identified through factor analysis, we comprehensively analyzed the image of science teacher desired by elementary school students in inquiry-based instruction. As a result of EFA, five factors were identified which compose the image of science teacher desired by elementary school students in inquiry-based instruction: namely, teaching strategy, assessment strategy, prior guidance, understanding students, learning development. The CFA results showed a relatively strong correlation between teaching strategy and learning development, teaching strategy and understanding students. As a result of a comprehensive review of students' perception of the image of science teachers in inquiry-based instruction based on the extracted factor structure, students perceived that it is important for science teachers to run inquiry-based instruction by reflecting their understanding of students. Students also perceived importantly that science teachers run inquiry-based instruction using effective teaching strategies and proper evaluation strategies.

The study aims to investigate the effects of media and self-image congruity of ideal body image on the dieting and exercising behaviors of Korean and U.S. female college students. This study focuses on the concept of self-image congruity in order to examine how respondents perceive actual and desired self-images compared to an ideal female body image selected by respondents. A self-administered survey was conducted, resulting in 331 total responses (194 from Korean students and 137 from U.S. students). The data were analyzed through descriptive analysis, t-test, exploratory factor analysis, and regression analysis using SPSS 23.0. The findings revealed significant differences between Korean and U.S. female college students. U.S. students were more exposed to body image ideals in the media than Korean students; however, Korean female students valued the information regarding ideal body image conveyed by the media more than U.S. respondents. Among Korean female students, exposure to media messages regarding ideal body image and media importance had significant effects on desired self-image congruity, while these factors were not significant among U.S. students. However, there was a negative effect of media exposure on actual self-image congruity among U.S. respondents only. Additionally, the study uncovered that Korean students manage their body image through dieting behaviors while U.S. respondents manage body image through exercise behaviors (weight training as well as cardiovascular exercise). The study provides further support for self-image congruity, which extends its applications to the body image field.

The problem of establishing the servo system to reach the desired location keeping all features in the field of view and following a straight line is considered. In addition, robustness of camera calibration parameters is considered in this paper. The proposed approach is based on switching from position-based visual servoing (PBVS) to image-based visual servoing (IBVS) and allows the camera path to follow a straight line. To achieve the objective, a pose estimation method is required; the camera's target pose is estimated from the obtained images without the knowledge of the object. A switched control law moves the camera equipped to a robot end-effector near the desired location following a straight line in Cartesian space and then positions it to the desired pose with robustness to camera calibration error. Finally simulation results show the feasibility of the proposed visual servoing technique.

Over the past three years, even amidst viral threats, a notable shift towards online interactions has been observed. This trend persists the presence of significant viral concerns. Our study centered on female office workers in their twenties and thirties in Korea, seeking to comprehend how they enhance and present their external image in the digital era. We explored the use of digital devices and fashion choices that enable them to amplify their self-expression in video conferences. Using a mix of surveys and in-depth interviews, we employed snowball sampling to recruit twelve participants. These women were given the opportunity to shape their digital persona either to uphold their current image or to adapt it for interactions where they weren't face-to-face. Their desired images fell into three distinct categories: an authoritative professional image, a clean modern image, and a natural image. Depending on the context, the participants aimed to convey these images independently or in various combinations. Our findings suggest the need to develop strategies for acknowledging and projecting individual fashion identities in non-face-to-face interactions. Such strategies would empower individuals to better align their online personas with their desired self-image, whether it's professional, modern, clean, natural, or a combination thereof.
