  • Elimination of dangerous points is the most effective method for safety in mechanical equipments. The next effective method is recognized as isolation and/or safe-guarding of dangerous spots from human beings. With progress of mechanical automation technique such as industrial robots, the need for safe-guard-ins is now being enlarged. It is needless to say that when a machine-guard is designed and installed, a comprechensive understanding of human movement is indispensable. But in this country, there is no scientific for those thems, and no one verifield whether it is valid to apply general guideline such as OSHA's to Korean or not. Further, basic anthropometric items for safety reach standards are neither availble nor included in nation-wide anthropometry project. In this research, human anthropometry data of Korean youngsters are analyzed for safety barrier and safety slit width, and compared with guidelines of other countries-Germany, United Kingdom, Japan, and USA. Though they are standards for safety, since they are based upon their own peoples' data, some of them especially foot reach are not not applicable in this country. It should be notified that careful application of numeric value is very important.

  • In this paper, we propose a real-time people tracking system with multiple CCD cameras for security inside the building. The camera is mounted from the ceiling of the laboratory so that the image data of the passing people are fully overlapped. The implemented system recognizes people movement along various directions. To track people even when their images are partially overlapped, the proposed system estimates and tracks a bounding box enclosing each person in the tracking region. The approximated convex hull of each individual in the tracking area is obtained to provide more accurate tracking information. To achieve this goal, we propose a method for 3D walking human tracking based on the IMPRESARIO framework incorporating cascaded classifiers into hypothesis evaluation. The efficiency of adaptive selection of cascaded classifiers have been also presented. We have shown the improvement of reliability for likelihood calculation by using cascaded classifiers. Experimental results show that the proposed method can smoothly and effectively detect and track walking humans through environments such as dense forests.

  • In modern times, text has become an image, and typography is a style that is a combination of image and text that can be easily encountered in everyday life. It is developing not only for the purpose of conveying meaningful communication, but also to bring joy and beauty to our lives as a medium with aesthetic format. This study shows through case analysis that typography is a tool for expressing human emotions, and investigates its characteristics that change along with the media. In particular, interactive communication tools and methods used by interactive typography to express viewers' emotions are described in detail. We created interactive typography using the inputted text, the selected music by the viewer and the viewer's movement. As a result of applying it to the exhibition, we could confirm that interactive typography can function as an effective communication medium that shows the utility of both the iconography of letter signs and the cognitive function when combined with the audience's intentional motion.

  • The pathological hallmark of rheumatoid arthritis (RA) is a synovial pannus that comprises proliferating and invasive fibroblast-like synoviocytes, infiltrating inflammatory cells, and an associated neoangiogenic response. Animal models have been established to study these pathological features of human RA. Spontaneous and induced animal models of RA primarily reflect inflammatory aspects of the disease. Among various induced animal models, collagen-induced arthritis (CIA) and collagen antibody-induced arthritis (CAIA) models are widely used to study the pathogenesis of RA. Improved transplantation techniques for severe combined immunodeficiency (SCID) mouse models of RA can be used to evaluate the effectiveness of potential therapeutics in human tissues and cells. This review provides basic information on various animal models of RA, including CIA and CAIA. In addition, we describe a SCID mouse coimplantation model that can measure the long-distance migration of human RA synoviocytes and cartilage destruction induced by these cells.

  • A walking navigation system (usually known as a locomotion interface) is an interactive platform which gives simulated walking sensation to users using sensed bipedal motion signals. This enables us to perform navigation tasks using only bipedal movement. Especially, it is useful for the certain VR task which emphasizes on physical human movement, or accompanies understanding of the size and complexity of building structures. In this work, we described system components of VR walking system and investigated several types of walking platform by literature survey. We adopted a MS Kinect depth sensor for the motion recognition and a treadmill which includes directional turning mechanism for the walking platform. Through the integration of these components with a VR navigation scenario, we developed a simple VR walking navigation system. Finally several technical issues were found during development process, and further research directions were suggested for the system improvement.

  • The purpose of this study is to analyse the diagrammatic design approaches and programmatic design approaches in contemporary architecture, so that this reveals the sequential systems of circulation in the space and liberal movement of the visitors in the buildings of those diagrammatic and programmatic architecture. Contemporary architecture generates the new forms and meanings through the dynamic visions and perspectives. Such a variation of sequential vistas and dynamic visions produce a perception of time and a potential movements of axis in the perspective. This study give the systematic body to the relations among visions, movements, sequences, forms, circulations and time. Diagrammatic and programmatic design approaches show the heterogeneous spaces and the informal architectures in contemporary architecture. Therefore, movements of various view points, differrentiations of objects in the perspectives, and multiple view frames appears in the designs of initiative architects. In conclusion, this study systemizes the concepts of time, sequential movements, and perceptions of events in contemporary architecture through the analyse of 18 architectural works of important architects in 2000s. And this shows details of the transitional movement of space and the perception of time in contemporary Architecture. The Being of the active time constructs formal transformations, spacial differentiations, accumulations of human behaviors, and movements of circulations involved with experiences of the field of senses. Therefore, Zeitlichkeit is perceived through concepts of the sequences of those spaces, forms, behaviors, and memories.

  • Putting his 'Panic theatre' aesthetics into practice, Fernando Arrabal is a leader of the avant-garde theatre. Creating ${\ll}$Guernica${\gg}$, Arrabal's play, in a dance theatre format, this study tries to analyze the group pathos in fanatical conscious and poetic movement. Logic analysis is based upon the pathos value of the theatre of the Absurd that transcends the unrealistic and the illogic on the authority of dual element of the internal opposition and contradiction of human beings. In ${\ll}$Guernica${\gg}$, the dance of the Absurd found expression in the group pathos phenomenon of fanatical conscious, and was analysed as a new framework of communication structure.

  • Behavioral sequences of the medaka (Oryzias latipes) were continuously investigated through an automatic image recognition system in response to medaka treated with the insecticide and medaka not treated with the insecticide, diazinon (0.1 mg/l) during a 1 hour period. The observation of behavior through the movement tracking program showed many patterns of the medaka. After much observation, behavioral patterns were divided into four basic patterns: active-smooth, active-shaking, inactive-smooth, and inactive-shaking. The "smooth" and "shaking" patterns were shown as normal movement behavior. However, the "shaking" pattern was more frequently observed than the "smooth" pattern in medaka specimens that were treated with insecticide. Each pattern was classified using classification methods after the feature choice. It provides a natural way to incorporate prior knowledge from human experts in fish behavior and contains the information in a logical expression tree. The main focus of this study was. to determine whether the decision tree could be useful for interpreting and classifying behavior patterns of the medaka.

  • Since science was first taught in schools, maybe during the 18th century, school science education has experienced many substantial changes in its goals and nature over the period. The historical changes are usually referred to by some key terms, like, mechanics' institutes, object lessons, heuristics, general science, inquiry, STS, misconceptions. To characterize these changes, science educators frequently use some slogan-like analogies, referring to parts of the human body to indicate the movement of science education during a particular period of time: for example, 'Hands-On' for inquiry movement during 1960s-70s, 'Minds-On' for constructivist movement during 1980s-90s. In this paper, we briefly summarize the overall historical development of science education in Britain, then further expand the analogies to cover the overall process, that is, Ears-On ${\to}$ Eyes-On ${\to}$ Hands-On ${\to}$ Minds-On. To illustrate future directions of the 21st century, we propose a new analogy, 'Hearts-On', and also discuss the meanings and implications of a 'Hearts-On' analogy by illustrating how this new paradigm can be applied to reflect various current trends of science education, particularly in Korea. In addition, a parallel historical change between school science and science museums & centres is discussed.

  • According to industrial disaster statistics by the Ministry of Labor in 2006, out of 11,688,797 people working at 1,292,696 business places that apply Industrial Disaster Indemnity Act, 89,910 workers were involved in an accident that more than 4 days of medical treatment requires. Among this figure 2,453 people lost their precious lives. "89,910 industrial disaster victims per annum" is showing the safety level of our industrial situation. To prevent such industrial disaster, the most typical and distinctive method is Accident-free Campaign. At the beginning, the movement arose with devotion through out the entire industry. But, the heartbreaking fact is that the fever is getting cool gown as times goes by. Therefore, opportunity for revitalization of this movement is required. The movement should be practically supporting principle of respect for human life and dignity. And it should be established with analysis on industrial disaster and systematize Accident-free Campaign totally in connected research.
