The space in today's digital era is developing in a new direction with the changing paradigm, which is different from that in the analog era. The space that appeals to the advanced technology mobilizes all the five senses of the space user with the technical elements of the more variable fields and aesthetic productions, and creates an interactive environment by motivating the user's active participation through the digital media. The environmental device called digital media connects the function pace with living performance. Unlike in the analog space, the different sides of the digital media space create a human consciousness that corresponds to the realistic ambience, further contributing to the lively condition. For the main production technique in the digital medias performance-active space, there are electronic image production, changeable production, impromptu-active production, light and sound production, and total artistic production that lead to the progressive interaction between man and space.

This research investigated the tourism resources strategies of royal tomb from the perspectives of Seosam-noung's social transfigurations and space characteristics. The result showed that environmental factors were no less important than cultural factors for evaluating royal tomb's recreational value. Because a royal tomb needs to be developed as a rest place for citizens, how citizen's rest place and tourism recreation can be coexisted is a significant matter for a space development. In addition, royal tomb's characteristic is related to the characteristics of culture, environment, man, gardening, and scenery. Therefore, the story research of these gardening, man, space needs to be investigated.

This paper presents a robust nonlinear controller for a f degree of freedom (DOF) parallel manipulator in the task space coordinates. The proposed control strategy requires information on orientations and translations in the task space unlike the joint space or link space control scheme. Although a 6 DOF sensor may provide such information in a straightforward manner, its cost calls for a more economical alternative. A novel indirect method based on the readily available length information engages as a potential candidate to replace a 6 DOF sensor. The indirect approach generates the necessary information by solving the forward kinematics and subsequently applying alpha-beta-gamma tracker With the 6 DOF signals available, a robust nonlinear task space control (RNTC) scheme is proposed based on the Lyapunov redesign method, whose stability is rigorously proved. The performance of the proposed RNTC with the new estimation scheme is evaluated via experiments. First, the results of the estimator are compared with the rate-gyro signals, which indicates excellent agreement. Then, the RNTC with on-line estimated 6 DOF data is shown to achieve excellent control performance to sinusoidal inputs, which is superior to those of a commonly used proportional-plus-integral-plus-derivative controller with a feedforward friction compensation under joint space coordinates and the nonlinear controller under task space coordinates.

Recently, hospital architecture has acknowledged remedial value of environment and atmosphere, which consider patient's statement of physical, spiritual, psychological and social focus, escape from the past focus of functional and rational space composition. The many research of hospital architecture just analyze elements of architectural planing which focus how to make a healing environment for patients. The purpose of this study is to abstract the design principle of architectural space composition for healing environment significance, through case study which follow up space composition. To abstract healing environment significance by space composition, each case study hospitals should be analyzed and estimated on the spatial composition elements. It is to provide the basic data for effective architectural planning of the hospital.

As we recognize the space, humans will experience a process to synthesize elements of cognitive various methods, come to understand the environment. It is intended that on humans to recognize the space, it is intended to act directly under study how to recognize. Humans can know that the determining action based on the values and physical condition, based on the space in which they have been recognized, there are differences in the behavior of the human as a result. Social and arrangement of components - physical region that is cultural difficulties constitute experience specific areas therein. Space for human activities and human, can know that it is not a memory of human behavior, to have a closer relationship with human perception. That is, the description will be aware of the space via the perceptual phenomenon of man due to physical elements performed in the space, what acts about what happens. Through an understanding of the potential for this, and emotion space production consisting only of physical visual element future, and use act of the area to be expressed from his recognition, through the expansion of the perceptual elements, diverse experience richer and more it is a case where deemed necessary access space configuration capable of a broad depth study of this portion is happening, in order to constitute a space, a new interpretation for human behavior is progressing.

Energy consumption has been increased world widely, and the energy retain is one of the most important economic alternatives. These tendencies expand the nuclear power plants not only quantitatively but also qualitatively. Despite of the increasing construction of nuclear power plants and related facilities, every system in main control room(MCR) has been designed and administered solely based on the safety-first principles because of the specificity of nuclear industry. However, recent main control rooms started with the concept that the operators' performance could be optimized though the organic interrelation between human, machine, and environments. Now, it has been recognised in the scope of Ergonomics and Space Design which acknowledge our living spaces as Man-Environment Interface and this change connotes the MCR spaces should be special spaces rather than ordinary spaces. This research investigated domestic and foreign nuclear power plants' MCRs to suggest basic alternatives which can be applied to future MCR. With the review of characteristics of MCR, an integration of interior design, lighting and Ergonomics was explored and classified as types. Futhermore, the classification of environmental characteristics within the relationships between human, machine, and environments was developed through the case analysis of nuclear power plants. The results of this study will provide a basis of space design for system environments that the high level of safety and function are extremely important.

Nature has provided inspiration for most of the man-made technologies. Scientists believe that dolphins are the second to humans in smartness and intelligence. Echolocation is the biological sonar used by dolphins for navigation and hunting in various environments. This ability of dolphins is mimicked in this paper to develop a new optimization method. Dolphin Echolocation Optimization (DEO) is an optimization method based on dolphin's approach for hunting food and exploration of environment. DEO has already been developed for discrete optimization search space and here it is extended to continuous search space. DEO has simple rules and is adjustable for predetermined computational cost. DEO provides the optimum results and leads to alternative optimality curves suitable for the problem. This algorithm has a few parameters and it is applicable to a wide range of problems like other metaheuristic algorithms. In the present work, the efficiency of this approach is demonstrated using standard benchmark problems.

Initial successful treatment of postpneumonectomy empyema depends to a large extent on adequate dependent drainage of the empyema sac and the use of antibiotics. But definite control of the infected space remains a disturbing and controversial area in the field of thoracic surgery. A 55-year-old man had a right pneumonectomy for tuberculosis with the development of postoperative thoracic empyema and in October 1973. Postoperatively, an empyema developed and the condition was managed with closed drainage and an open window thoracostomy. He was transferred to our institution in October 1988, and underwent thoracoplasty for the obliteration of the empyema space, resulting in a remaining space. The remaining space after thoracoplasty was obliterated by myoplasty using a rotation flap of splitted pectoralis major muscle three months later. He was discharged with uneventful course 12 days after operation, and continues to do well 3 months following operation. Our experience shows that thoracoplasty and myoplasty offer an effective alternative method of management of post-pneumonectomy empyema.

In this paper, a distance measuring algorithm for motion capture using color stereo camera is proposed. The color markers attached on articulations of an actor are captured by stereo color video cameras, and color region which has the same color of the marker's color in the captured images is separated from the other colors by finding dominant wavelength of colors. Color data in RGB (red, green, blue) color space is converted into CIE (Commission Internationale del'Eclairage) color space for the purpose of calculating wavelength. The dominant wavelength is selected from histogram of the neighbor wavelengths. The motion of the character in the cyber space is controlled by a program using the distance information of the moving markers.

Purpose: As the medical laboratories in general hospitals have made an efforts on quality management and employee health, they recognized the need of design guideline for clinical laboratory. As laboratories are prohibited to patients, their environments are becoming more congested and deteriorated as time goes by. So, this study investigates the current status of facility and equipment of laboratory medicine focusing on less than three hundred patient bed hospitals, and searches the improving matters. Methods: Questionnaires to technologist captains and field surveys to medical laboratories in korean hospitals have been conducted for the data collection. 18 answers have been analysed statistically by MS Excel program. Results: The result of this study can be summarized into followings. Clinical laboratory functions are all hematology, clinical chemistry, immunology, transfusion and urine microscopy, and except for three including microbiology for infection and bio safety level. Average man power of lab are 12.3 man including lab director and captain. Patient bed number, space area and total specimen numbers are not correlated with each other, but specimen numbers and employee number are correlated with. Work space distances are usually good, but exit distances are not adequate for escape owing to obstacles. Specimen delivery system by courier, test method by automatic analyzer, access floor for exposed plumbing and electricities are more practical. Open lab layed out in the center and lab support layed peripheral in space diagram. Lab space configuration by SD method showed that lab support area and employee support area are dissatisfied. Implications: Specialized hospital and yearly total specimen numbers are related to the space area and organization for laboratory planning and design.
