  • The rifle impact of human body affected by the posture of human for rifling. The interaction human-rifle system influence the firing accuracy. In this paper, impact analysis of human model for shooting posture is carried out. ADAMS code and LifeMOD is used in impact analysis of human model and modeling of the human body, respectively. On the shooting, human model is affected by rifle impact during the 0.001 second. Performed simulation time for shooting is 0.1 second. Applied constraint condition to human-rifle system is rotating and spherical condition. As the results, the displacement of rifle and transfer path analysis of impact of human model is presented.

  • Humans usually employ more joints than they actually need, and thus they can be categorized as a kinematically redundant system. Therefore, the behavior of the human body can be analyzed by several redundancy resolution algorithms. Different from typical industrial robots that are fixed to the ground, the COG/ZMP condition should be taken into account in the human body motion in order not to fall down. Thus a COG/ZMP stability index is employed as a measure of stability. Kinematic redundancy inherent in the human body can be exploited to satisfy the COG/ZMP condition. Simulation result shows that the COG/ZMP condition can be satisfied by exploiting the null space motion of the kinematically redundant human body model.

  • If an appliance perceives the location or health condition of a resident in the smart home, it can provide more intelligent service actively. That is, while the conventional appliance is operated by manual input of a resident, the location-based human adaptive appliance detects the resident's information such as location, activity pattern, or health condition by itself and provides the most suitable living condition for the resident autonomously. This paper presents the real-time location-based metabolic rate estimation method that measures the amount of physical activity (metabolic rate) for location-based human adaptive air-conditioner. And, the feasibility of the algorithm is evaluated experimentally on a test bed using the pyroelectric infrared sensor-based indoor location aware system (PILAS) that is a non-terminal-based location-aware system.

  • After studying the theory of JangBu(臟腑), that is a physiology of Sasang Constitutional Medicine, in Sasang Constitutional Medicine, the author could draw a conclusion as these. 1. The basic thought of Sasang Constitutional Medicine is emphatic on the human beings itself unlike the idea of traditional Oriental Medicine, that accentuate the universe.(The traditional Oriental Medicine has a concept that the human beings follows the order of universe, but Sasang Constitutional Medicine has a different idea that human beings has the free will to the universe and newly comprehend the relationships between human beings and universe.) 2. Like the preceding, the theory of JangBu(臟腑), the physiology of Sasang Constitutional Medicine, is based on the autonomic mechanisms of human body itself. 3. The medical philosophy of Sasang Constitutional Medicine is Sasang(四象), that is Sa(事), Sim(心), Sin(身) and Mul(物). This Sasang is a classification of universe include human beings.(Sa(事) is event, Sim(心) is mind, Sin(身) is body, and Mul(物) is things. these four elements express the universe and human.) 4. The JangBu(臟腑) theory of Sasang Constitutional Medicine regard mind condition as important. The mind condition is divided into two factors. The one is Seong(性) the other is Jeong(情). The Seong(性) is an attitude toward the world, and the Jeong(情) is response to the stimulation from the world. 5. By the actions of Seong(性) and Jeong(情), the human body has different JangBu(臟腑) function, so the human body can be grouped in four constitutions. 6. Because of emphasis on mind condition, the Sasang JangBu(臟腑) theory has activism of human beings itself. 7. This activismor practical philosophy of Sasang JangBu(臟腑) theory, that is a physiology of Sasang Constitutional Medicine, gave birth to ethics or morality in Medical philosophy, that the human practice of ethics or morality bring a health and well being of human body.

  • The purpose of this study is to seek a new understanding of human beings by examining, through the various types of futuristic humans in SF narratives, the changes of human condition and identity, raised by the discussion on the posthuman today. The rapid development of science and technology blurs the line between humans and machines, predicting the birth of the 'new human posterior to the human'. The advancement of technology enables the production of 'human beyond the biological human' through the combination of humans and machines, and humans are becoming more mechanized. On the other hand, machines are gradually developing to the stage of resembling not just the exterior body structure, but the thinking abilities and emotions of human beings. However, by colliding with the traditional view of human beings, artificial changes to the human condition as a result of cutting-edge technology demand a new perspective on the meaning of a new being and changes in human conditions. Therefore, the study examines how human conditions and perceptions have changed in accordance with the evolution of science and technology, and then explores the direction of co-evolution between humans and machines through the various types of futuristic humans that appear in the SF narratives, as well as the potential of futuristic humans as the new subject.

  • Knowledge-based services are largely dependent upon human-driven works. Therefore, considering human characteristics is required when modeling processes for knowledge-based services. As an emerging technology for Business Process Management, Human Interaction Management and its supportive process management can be an alternative to deal with human-driven processes. However, current HIM does not suggest concrete method for modeling conditions that are essential to realize supportive process management. And the condition modeling of HumanEdj, the only HIM software implemented, reveals the problem of complexity. As a solution, this paper suggests a fact-oriented ontological approach to process modeling. The approach uses human-friendly form of facts for condition modeling.

  • This paper deals with modeling and analysis fer the landing motion of a human-body model. First, the dynamic model of a floating human body is derived. The external impulse exerted on the ground as well as the internal impulse experienced at the joints of the human body model is analyzed. Second, a motion planning algorithm exploiting the kinematic redundancy is suggested to ensure stability in terms of ZMP stability condition during a series of landing phases. Four phases of landing motion are investigated. In simulation, the external and internal impulses experienced at the human joints and the ZMP history resulting from the motion planning are analyzed for two different configurations. h desired landing posture is suggested by comparison of the simulation results.

  • Human embryonic stem (ES) cells are a potential source of cells for developmental studies and for a variety of applications in transplantation therapies and drug discovery. However, human ES cells are difficult to culture and maintain at a large scale, which is one of the most serious obstacles in human ES cell research. Culture of human ES cells on MEF cells after disassociation with accutase has previously been demonstrated by other research groups. Here, we confirmed that human ES cells (H9) can maintain stem cell properties when the cells are passaged as single cells under a feeder-free culture condition. Accutase-dissociated human ES cells showed normal karyotype, stem cell marker expression, and morphology. We prepared frozen stocks during the culture period, thawed two of the human ES cell stocks, and analyzed the cells after culture with the same method. Although the cells revealed normal expression of stem cell marker genes, they had abnormal karyotypes. Therefore, we suggest that accutase-dissociated single cells can be usefully expanded in a feeder-free condition but chromosomal modification should be considered in the culture after freeze-thawing.
