The design of seat is maintaining to final stable posture. The final stable posture is the seated posture in which the force of the pad and spring supporting the body is balanced with the body weight and the bodydoes not sink anyfurther intothe seat. With poorly designed seated seats, your behind maygradually move forward, or localized pressure may result in congestion of the blood or numbness, making you want to move. Therefore, the final stable posture is not maintained. A number of ideas were used in this study will eliminate this problem. In automobile seat design, primary attention has forcused on providing the occupant with a comfortable seat that has sufficient padding and adjuxtments toaccomodate different sizes and postures of people. First of all, whether the process is design-oriented or technology-oriented, the design concept must be human-oriented. The fatigue-alleviating seats which were the primary purpose of this research were studied with a human-oriented approach.

Static electricity in electronics manufacturing plants causes the economic loss, yet it is one of the least understood and least recognized effects haunting the industry today. Today's challenge in semiconductor devices is to achieve greater functional density pattern and to miniaturize electronic systems of being more fragile by electrostatic discharges(ESD) phenomena. As the use of automatic handling equipment for static-sensitive semiconductor components is rapidly increased, most manufacturers need to be more alert to the problem of ESD. One of the most common causes of electrostatic damage is the direct transfer of electrostatic charge from the human body or a charged material to the static-sensitive devices. To evaluate the ESD hazards by charged human body and devices, in this paper, characteristics of electrostatic attenuation in domestic semiconductor devices is investigated and the voltage to cause electronic component failures is investigated by field-induced charged device model(FCDM) tester. The FCDM simulator provides a fast and inexpensive test that faithfully represents ESD hazards in plants. Also the results obtained in this paper can be used for the prevention of semiconductor failure from ESD hazards.

In this work the kinetics of volume changes of fluid spaces associated with infusion of Ringer's solution are analyzed using the body fluid space model. During infusion of Ringer's solution, the human body is assumed to be characterized by the fluid space model into which fluid is fed and from which fluid is left. Various infusion types were tested to accommodate different medical situations. Volunteers were given Ringer's solution and the changes in blood hemoglobin were detected. From the comparison with experimental data, the single- and two-fluid space models were found to represent adequately the kinetics of human volume expansion during infusion of Ringer's solution.

In computer vision research, the two-dimensional human pose is a very extensive research direction, especially in pose tracking and behavior recognition, which has very important research significance. The acquisition of human pose targets, which is essentially the study of how to accurately identify human targets from pictures, is of great research significance and has been a hot research topic of great interest in recent years. Human pose recognition is used in artificial intelligence on the one hand and in daily life on the other. The excellent effect of pose recognition is mainly determined by the success rate and the accuracy of the recognition process, so it reflects the importance of human pose recognition in terms of recognition rate. In this human body gesture recognition, the human body is divided into 17 key points for labeling. Not only that but also the key points are segmented to ensure the accuracy of the labeling information. In the recognition design, use the comprehensive data set MS COCO for deep learning to design a neural network model to train a large number of samples, from simple step-by-step to efficient training, so that a good accuracy rate can be obtained.

In this paper, we describe interactive contents which is used the result of the inputted interface recognizing vision-based body gesture. Because the content uses the imp which is the common culture as the subject in Asia, we can enjoy it with culture familiarity. And also since the player can use their own gesture to fight with the imp in the game, they are naturally absorbed in the game. And the users can choose the multiple endings of the contents in the end of the scenario. In the part of the gesture recognition, KINECT is used to obtain the three-dimensional coordinates of each joint of the limb to capture the static pose of the actions. The vision-based 3D human pose recognition technology is used to method for convey human gesture in HCI(Human-Computer Interaction). 2D pose model based recognition method recognizes simple 2D human pose in particular environment On the other hand, 3D pose model which describes 3D human body skeletal structure can recognize more complex 3D pose than 2D pose model in because it can use joint angle and shape information of body part Because gestures can be presented through sequential static poses, we recognize the gestures which are configured poses by using HMM In this paper, we describe the interactive content which is used as input interface by using gesture recognition result. So, we can control the contents using only user's gestures naturally. And we intended to improve the immersion and the interest by using the imp who is used real-time interaction with user.

Reliable tracking of moving humans is essential to motion estimation, video surveillance and human-computer interface. This paper presents a new approach to human motion tracking that combines appearance-based and model-based techniques. Monocular color video is processed at both pixel level and object level. At the pixel level, a Gaussian mixture model is used to train and classily individual pixel colors. At the object level, a 3D human body model projected on a 2D image plane is used to fit the image data. Our method does not use inverse kinematics due to the singularity problem. While many others use stochastic sampling for model-based motion tracking, our method is purely dependent on nonlinear programming. We convert the human motion tracking problem into a nonlinear programming problem. A cost function for parameter optimization is used to estimate the degree of the overlapping between the foreground input image silhouette and a projected 3D model body silhouette. The overlapping is computed using computational geometry by converting a set of pixels from the image domain to a polygon in the real projection plane domain. Our method is used to recognize various human motions. Motion tracking results from video sequences are very encouraging.

In Korean Traditional Medicine(K.T.M.)'s theory, there are some important constitutions which constitute the human being. They are Jeong(精), Gi(氣), Sin(神), and Hyeol(血). Jeong(精) is the essential substances which constituting human body and maintaining life's activities. Gi(氣) is the vital energyor functional activities of human body. Sin(神) is a kind of Gi(氣) which is related to mentality, consciousness and thinking. Hyeol(血) is the red fluid circulating through the blood vessels and nourishing the body tissues. When a man is born, he takes Jeong(精) from his father, and Hyeol(血) from his mother. So father' s Jeong(精) and mother' s Hyeol(血) became the source of their children's Jeong(精), Gi(氣), Sin(神), Hyeol(血). But after be borning, man need to make Jeong(精), Gi(氣), Sin(神), Hyeol(血) by himself from Foods and drinks[水穀]. This thesis was written to explain a process or a system how the Foods and drinks[水穀] change to human's Jeong(精), Gi( 氣), Sin(神), Hyeol(血). When the food and drink[水穀] put in human's mouth, Five Bu[五腑] primarily digest and change to food and drink[水穀]'s Essence and nutrients which is similar to chyme or chyle[乳廳]. Secondarily, Five Jang[五臟] make Gi(氣), Jinaek(津液) - the body fluid, Jeong(精), Wigi(衛氣) - the defensive Gi, and Yeonggi(營氣) - the nutrient Gi circulating the Meridians, and Hyeol(血) from that food and drink [水穀]'s Essence and nutrients. And the information of every processing is reflected in urine. 50 the digestion is accomplished at not only Five Bu[五腑] but also five Jang[五臟]. The concept of digestion in this thesis is including both catabolim[異化作用] and anabolism [同化作用]. Samcho(三焦) is the recognition to the process of this digestion - ctabolism and anabolism in three part.

To achieve a cooperative work between human and robot, it is thought helpful to estimate the states of human mind, which originates his behavior. In this paper, human mind was considered to modify instinctive desires according to the conditions of external world surrounding the instinct. A simple human mind model was designed so that it finds a balance between instinctive desire and restriction from the external world. The external world is divided into three sub-worlds like subject´s whole body, its partner and concerned periphery. Proposed mind model has three-layers construction. Each of the layer tries to find a balance between desire and restriction from external world. In each layer, the role of finding the balance was expressed by an identical optimal control minimizing a performance index function of quadratic form with a weight factor, which is rearranged and named ...

Chicken not only serves as a high-protein source to humans, but it is also used as a suitable biomodel for increasing livestock productivity and studying human diseases. Chickens have numerous advantages as model organisms mainly because of they are relatively convenient to manage due to their small body size and short generational interval. In addition, they have a small genome size and numerous genes have biologically similar functions to those of human and livestock animals. In this review, we investigated the chicken biomodel for human disease research and the use of this model for increasing livestock productivity. This summary could provide useful and basic information for further development of strategies for enhancing livestock production and human disease studies.

This research aims at developing the dress form for the aged women based on their body shapes using the three-dimensional body scan data with the body shape categorization(according to the previous research). To accomplish this goal, the sample group of representative body shape of the 50% of median was selected by using the high frequency proportion range of each type of body shape of the aged women, and the sample group of representative body shape of each type was averaged in a three-dimensional way by using the morphing method of a three-dimension reverse-engineered software. RP in the form of torso was produced based on the shape data of the final model and the data was formed into an actual object, by which an aged women's dress form model was drawn out. The differences of the girth of the bust, hip and waist between the developed dress form model and the existing dress form model were examined. The result showed that the developed dress form had a bigger size of waist girth than that of bust and hip girth, compared to the existing dress form, which shows that it reflects the aged women's tendency of abdomen obesity, so it's expected to be more proper for the human bodies of the targeted age group than the existing dress form. These research results may help design the clothing suitable for the body shape of the aged women so that their demand for the clothing of good fit will be satisfied in the future.
