In this paper, a novel type of a visual servoing method is proposed for eye-in-hand robots by employing a self-organizing fuzzy controller. For this is there defined a new Jacobian riot to be the function of a relative position of the object but to be a function of the only image features. Instead of obtaining an analytic form of the proposed Jacobian, a self-organizing fuzzy controller is then proposed to alleviate difficulties in real-time implementation. To show the validities, the proposed method is applied to a 2-dimensional visual servoing task.

This paper proposes efficient cloth animation and collision handling methods. There have been various techniques for the generation of cloth behavior. However, the cloth animation is still a challenging subject in real-time environments. This paper presents an efficient animation method based on implicit integration. The proposed method can efficiently animate virtual cloth object with complex geometry. In addition, this paper also introduces an efficient collision handling method. The collision resolution is another important issue in cloth animation since deformable objects has special collision problem called self-collision. In this paper, the self-collision was successfully avoided in real - time environments.

This study aims to analyze the effect of transformational leadership (TL), procedural justice (PJ), and training (T) on employee performance (EP) mediated by self-efficacy (SE). The object of this research is Rumah Sakit Umum Daerah (RSUD) M.Th. Djaman, a hospital in Sanggau Regency, while the subjects are the institution's staff. Data collection search uses purposive sampling with a total of 120 samples. Data are obtained through questionnaires distributed directly to respondents using the Google Form application. Data analysis techniques used in this study include standard error of mean (SEM) with AMOS software version 24.00. Methods use to test validity and reliability of data include Confirmatory Factor Analysis (CFA), Construct Reliability (CR) and VE. The results of the analysis show that only training has a significant effect on self-efficacy, and self-efficacy has a significant effect on employee performance. Also, self-efficacy is proven to mediate the role of training on employee performance; the other hypotheses are not significant. Training is the most prominent positive factor affecting self-efficacy and self-efficacy has a significant effect on employee performance at RSUD M.Th. Djaman. The results of this study can be used as a reference by management in determining what policy priorities should take precedence.

Cousumers developed self-image through clothing symbolic product for reveal one’self image. When consumers select particular brand of various brand in the market that congruent with one’self image. They have to continue image. In this purpose, the research model was constituted and the questionnaire was made, reviewing preceding studies on self-image, shopping orientation. As for the method of the research, 635 female consumers were the object for the data of this research. The major results of this were as follows: 1. The factor or real self-image was composed of four factors: the refined and deluxe image, casual and simple image, decorous and dressy image, quiet and feminine image. 2. The consumer with real self-image were classified three groups: the group of feminine and dressy image 288 persons, the group of casual image 167 persons and poor image 171 persons. In the consumer’s classified real purchasing brand-image the group of feminine and dressy image was given higher score at feminine and refined and deluxe image, the group of casual image was given higher score at casual and active. 3. The factor of shopping orientation was composed of four factors: pleasant, planned, loyal, recreational shopping orientation. The group of feminine and dressy image was given higher score at pleasant and planned shopping orientation, the group of casual image was given lower score loyal and confident shopping orientation than the other group.

We aimed to analyze the effects of Kinesio-Taping on pain, satisfaction, and gait, and to provide basic data on the self-application of this method. The participants were 30 adult women with chronic low back pain. Kinesio-Taping was applied for 2 weeks, followed by 4 weeks of self-application education and self-application. The participants' pain levels were analyzed using the visual analog scale, satisfaction was analyzed using the Canadian Occupational Performance Measure, and gait was analyzed in terms of stride length, step length, step width, and gait time using the Walkway MG-1000 gait analyzer. The results of the pain showed the statistically significant decrease steadily (p<0.001) and the results of the satisfaction showed the statistically significant increase steadily (p<0.001) from the application of the Kinesio-Taping. Also, according to the In-Object verification between pre-test, taping application (after 2 weeks) and Self-application (after 4 weeks), the results of the satisfaction showed statistically significant difference (p<0.001). According to the gait analysis, the results of the stride length and step length showed the statistically significant increase steadily (p<0.001) and the results of the step width and gait time showed the statistically significant decrease steadily (p<0.001) from the application of the Kinesio-Taping. Also, according to the In-Object verification between pre-test, taping application (after 2 weeks) and Self-application (after 4 weeks), the results of the step width showed statistically significant difference (p<0.001). Thus, the self-application education about the Kinesio-Taping should be considered to reduce the pain and improve the performance level of the activities of daily life through the improvement of the self-management ability and to induce the active participation in the self-management activities and increase the satisfaction.

In this paper, we describe the new unsuperivised learning algorithm, SASOM. It can solve the defects of the conventional SOM that the state of network can't converge to the minimum point. The proposed algorithm uses the object function which can evaluate the state of network in learning and adjusts the learning rate flexibly according to the evaluation of the object function. We implement the simulated annealing which is applied to the conventional network using the object function and the learning rate. Finally, the proposed algorithm can make the state of network converged to the global minimum. Using the two-dimensional input vectors with uniform distribution, we graphically compared the ordering ability of SOM with that of SASOM. We carried out the recognitioin on the new algorithm for all Korean phonemes and some continuous speech.

Recently, object detection is a critical function for any system that uses computer vision and is widely used in various fields such as video surveillance and self-driving cars. However, the conventional methods can not detect the objects clearly because of the dynamic background change in the beach. In this paper, we propose a new technique to detect humans correctly in the dynamic videos like shores. A new background modeling method that combines spatial GMM (Gaussian Mixture Model) and temporal GMM is proposed to make more correct background image. Also, the proposed method improve the accuracy of people detection by using SVM (Support Vector Machine) to classify people from the objects and KCF (Kernelized Correlation Filter) Tracker to track people continuously in the complicated environment. The experimental result shows that our method can work well for detection and tracking of objects in videos containing dynamic factors and situations.

This paper presents a new method for automatically calibrating robot link (Kinematic) parameters during the process of estimating motion parameters of a moving object. The motion estimation is performed based on stereo cameras mounted on the end-effector of a robot manipulator. This approach significantly differs from other calibration approaches in that the calibration is achieved by simply observing the motion of the moving object (without resorting to any other external calibrating tools) at numerous and widely varying joint-angle configurations. A differential error model, which expresses the measurement errors of a robot in terms of robot link parameter errors and motion parameters, is developed. And then a measurement equation representing the true measurement values is derived. By estimating the above two kinds of parameters minimizing the difference between the measurement equations and the true moving pattern, the calibration of the robot link parameters and the estimation of the motion parameters are accomplished at the same time.

This study set out to analyze James Turrell's Skyspace works by applying the object relations theory, compare them with several modern architectural works with a sky window based on the analysis results, and check common and differentiating features between them. The findings were as follows: first, Turrell's Skyspace works shed new light on the images of the sky by projecting inner light to the outside; second, sky windows in architecture make the self-representation of inner space clear through the introjection of light; third, 'Hill of the Buddha' reflects the most general aspect of the object relations theory as the nature of projection found in Turrell's Skyspace is added to it; and finally, Turrell installed event-like spaces and steps in 'Roden Crater' to apply the introjection of others that was deficient in Skyspace.
