The design of optimal filter yielding optimal texture feature separation is a most effective technique in many torture analyzing areas, such as perception of surface, object, shape and depth. But, most optimal filter design approaches are restricted to the issue of computational complexity and supervised problems. In this paper, Our proposed method yields new insight into the design of optimal Gabor filters for segmenting multiple texture images. The optimal frequency of Gator filter is turned to the optimal frequency of the distinct texture in frequency domain. In order to show the performance of the designed filters, we have attempted to build a various texture images. Our experimental results show that the performance of the system is very successful.

In this paper, the prototype of a walking guide robot with tactile display is introduced, and the psychophysical experiment of the tactile recognition for a tactile display is carried out and analyzed. The objective of this research is the development of a walking guide robot for the blind to walk safely. A walking guide robot consists of a guide vehicle and a tactile display device. A guide vehicle, located in the front of the walking blind, detects the obstacle using ultrasonic sensors and offers the information of position and walking direction acquired from GPS module to the walking blind by voice. The tactile display device, located in the handle which is connected with the guide vehicle by cane, offers the processed obstacle information such as position, size, moving, shape of obstacle and safe path, etc. The psychophysical experiments for the threshold of perception and recognition ability of tactile stimulation are carried out by the estimation of the subject group. As a result the appropriate tactile stimulus intensity and frequency to recognize tactile stimulation effectively are discussed and derived.

Purpose: This study was carried out to find factors affecting weight-control behavior intention in female college students based on the theory of planned behavior. Methods: The subjects were 453 female students from everywhere other than the Gangwon Province and Jeju Island. Data were collected by using a questionnaire. Results: The factors affecting weight-control behavior intention in female college students within 2 weeks were attitudes and subjective norms. These two factors accounted for 20.0% of weight-control behavior intention. Also, when body shape satisfaction and BMI were added to variables of the theory of planned behavior like attitudes, subjective norms, and perceived behavior control, these 5 factors accounted for a total of 34.1%. Conclusion: Due to their distorted perception in preferring skinny body shapes, female college students are likely to attempt at inappropriate weight control behavior. Through intervention with such factors as attitudes and body image satisfaction, which have been derived from the results of this study, healthy weight control behavior should be pursued in practice.

Animation has been developed as a part of artistry, and maintained a correlation with other various genres such as art, film and music to bring changes in form and to seek new things. Recently, technological advancement also has supported digitalization of producing process with variety in its method. Basic unit of animation production is a frame. A set of frames which has an image of producer's intention comes to life as animation when constructed, connected and transformed. A producer usually goes through a series of trouble when deciding how to express one's intention in images. Framing in animation is a kind of visual information which reflects producer's visual perception. A producer does not simply characterize matters into geometrical figures or give circumstantial explanation, but does framing work that relies on expression. Artistic psychology based on Gestalt Theory does not concentrate on abstract artistic philosophy with conventional beauty as its center, but pursues ambiguity and coherence of formative arts to support on accepting systematic order. Therefore, the purpose of this study is to find theoretical assistance which may be fundamental part in framing of animation. First, ten elements of Rudolf Arnheim centering on Gestalt Theory shall be redefined as concepts. Based on its ground, I will attempt to analyze shape-quality of framing of conventional animation, and make an approach with my personal experimental project. From this research project, I intend to analogize systematic aspect of framing in animation and to make framing of animation possible to assist in actual production of animation.

Purpose: The purpose of this study was to identify parental coping strategies in the face of early infant and toddler injury, and to provide basic data for a parental education program and the most desirable directions it should take. Methods: A Q-methodology to analyze the subjectivity of each item was used. Thirty-four Q-statements were derived from a literature review and interviews. Forty-seven parents were classified into a shape of normal distribution using a 9-point scale. Collected data were analyzed by the pc-QUANL program. Results: Five types of parental coping in early infant and toddler injury were identified. Type I was "hospital treatment focused", type II was "Improving the safety of the child's environment", type III was "expression of negative emotion", type IV was "taking the lead in problem solving", and type V was "Interrogating the person in charge of the situation in which the injury occurred". Conclusion: The results of this study indicate that different approaches to educational programs can be used for parents in early childhood injury.

This study was undertaken to compare the obesity related dietary factors among rural middle school students living in the Daegu.Kyungbuk area. Anthropometric data showed that mean height and weight were 162.7$\pm$8.6cm and 53.9$\pm$9.8kg in 220 male students and 158.4$\pm$6.2cm and 51.0$\pm$7.6kg in 210 female student. Mean BMIs for boys and girls were 19.00$\pm$2.35 and 19.30$\pm$2.45, respectively. 71.36% of male students and 71.9% of female students were underweight by the BMI index. Students who skipped the breakfast were up to 66.8%. The reasons for skipping a meal for both sexes were significantly different. Compared to males, more female respondents felt guilty and depressed related to eating. Furthermore, females were more significantly concerned about body image, diet and body weight (p<0.001), and they were not satisfied with their weight. The sources of information on obesity and diet were radio and TV in males, while females gathered information from magazines and friends. The ideal body weight of male students was heavier than the actual body weight while female students desired a thinner body shape. In conclusion, a different approach for nutrition education based on sex should be developed, and implemented fur adolescents.

This study was started with concern about problem of increasing physical and personal injury caused by traffic accidents, despite of technological advances in transportation. As the vehicles, which is currently produced, informs the driver only detecting the proximity of an object by the front and rear sensor, this study implemented the color detection algorithm, the circular shape recognition algorithm, and the distance recognition algorithm and built the accident prevention beyond accident perception, which commends to avoid the object or to stop the robot, if object was detected by algorithms. For the simulation, we made the Arduino vehicle robot equipped with compact wireless communication camera and confirmed that the robot successfully avoids an object or stops itself in simulated driving.

As an adaptive control function generator, the CMAC (Cerebellar Model Arithmetic or Articulated Controller) based learning control has drawn a great attention to realize a rather robust real-time manipulator control under the various uncertainties. There remain, however, inherent problems to be solved in the CMAC application to robot motion control or perception of sensory information. To apply the CMAC to the various unmodeled or modeled systems more efficiently, It is necessary to analyze the effects of the CMAC control parameters an the trained net. Although the CMAC control parameters such as size of the quantizing block, learning gain, input offset, and ranges of input variables play a key role in the learning performance and system memory requirement, these have not been fully investigated yet. These parameters should be determined, of course, considering the shape of the desired function to be trained and learning algorithms applied. In this paper, the interrelation of these parameters with learning performance is investigated under the basic learning schemes presented by authors. Since an analytic approach only seems to be very difficult and even impossible for this purpose, various simulations have been performed with prespecified functions and their results were analyzed. A general step following design guide was set up according to the various simulation results.

It is fundamental to count and pack the pills in the medicine manufacture field but those tasks are time and labor consuming. Thus, the need fur automation of those tasks is necessarily getting increased in order to get effective mass production. It Is significant to perceive pills quickly and precisely. There were many trials for this processing but the performance of the existing counting machines varies about size, shape and dispersion tendency of pills. In this paper, the authors try to improve the counting performance of a pill counting machine that has optical sensors with the neural network. The passing signal of pill is acquired with optical sensor and the passage signal of the pill is extracted as input patterns. The gradient and integration of signal during passing time and the time keeping the pill interrupt the light from the LED are used as characteristic feature. The back propagation and perception algorithm are used for training. Experimental results with several pills show that the designed algorithm is a little bit effective to reduce the noise effect which is generated from interference among the machine components and unreliable environment.
