There have been many studies and experiments regarding exhibition lighting. Many experiments on photochemical damaging effect and visibility resulted in a practice limited to assigning light levels and adjusting annual exposure time. The three damaging factors to the artifacts are intrinsicsusceptibility to absorb radiant energy, spectral distribution of light source and intensity of illumination and time of exposure. Dividing all the artfacts into three categories to suggest a recommended illuminance level causes some problems. Blue wool, for example, used as the reference material for susceptibility, is not a standard material representing museum artifacts. In the most light sensitive category, ISO class I or anything below have been excluded. The exposure time of one soure can be three times more than another sourece. The spectral distribution of the light source and the relative spectral responsibility of the artifact are not considered in the practice. So in case of very light sensitive material, the recommended illuminance is only the referring value and it is indispensable to check the characteristic of susceptibility of each artifacts. Daylighting is prevailing method to solve the psychological need of the visitors. However, it sould transparent, and should not diffused, and the green-house effect must be considered. llluminance uniformity should based on the maximum illuminance to handle the limitation of exposure for the conservation of a large sensitive object such as a painting. Damage index is not absolute reference for selecting the lighting source because it is experimented from the paper of low grade then calculated. Visibility should be increased by reducing the visual noiseand by planning of appropriate luminance contrast. This paper reviews the problems with the previous studies and experiment sand the current exhibition lighting design practice. The plan for museum showcase lighting is to check the susceptibility and to raise the visibility simultaneously.

In interactive environments including computer games and virtual reality applications, we have increased need for interactive control of articulated body motions. Recently, physically based methods including constrained dynamics techniques are introduced to this area, in order to produce more realistic animation sequences. However, they are hard to achieve real-time control of articulated bodies, due to their heavy computations. In this paper, we present a procedural method for interactive animation of articulated bodies. In our method, each object of the constrained body is first moved according to their physical properties and external forces, without considering any constraints. Then, the locations of objects are adjusted to satisfy given constraints. Through adapting this two-stage approach, we have avoided the solving of large linear systems of equations, to finally achieve the interactive animation of articulated bodies. We also present a few example sequences of animations, which are interactively generated on PC platforms. This method can be easily applied to character animations in virtual environments.

This paper will discuss about how we can foster educational support mechanisms to facilitate health promotion programs at the local level. Health promotion in Korea is in the early developmental stage; it has only been since the Health Promotion Act was legislated in 1995, the health promotion programs have been planned and implemented. In the context of the recent decentralization process, local health departments have a major responsibility for developing and implementing health promotion programs at the local level. The short history of health promotion in Korea has meant that local public health departments have limited experience and organizational capacity for health promotion planning ＆ practice. The results of one survey for investigating the progress of health promotion at the local level are instructive. The survey demonstrated that the public health workers recognized that the lack of personnels, insufficient budget, the lack of policy ＆ the organizational support, the lack of skill ＆ knowledge to be effective health promotors, the lack of guidance for health promotion practice were major barriers to implementing health promotion programs at the local level. The object of this paper is to suggest some ways of overcoming barriers to implementing health promotion programs at the local level This paper emphasizes on the importance of educational supports as well as environmental supports - legislative, policy, organizational, economical - in building the organizational capacity and infrastructure of local health department for health promotion. It suggests some ways of providing educational supports to the public health workers at the local level. and supports the positions that educational opportunities for training in health promotion can be better provided to the public health workers at the provincial level rather than at the national level. It argues that the educational ＆ training programs should be developed and based on the educational need assessment; that the application of the main educational principles ＆ theoretical models for health promotion be used to develop educational programs for the public health workers; and that professional health organizations should make plans to provide more educational programs at their annual conferences or at other convenient times. These kinds of educational supports facilitate the ability of public health workers to improve their capacity for health promotion practice at the local level and help to alleviate some of the pressure on state resources.

Since Augmented Reality (AR) enables users to experience computer-generated content embedded in real environments, AR agents can be visualized among physical objects in the environments where the users exist, and directly interact with them in real-time. We model perceptual attention for autonomous agents in AR environments where virtual and physical objects coexist. Since such AR agents must adaptively perceive and attend to surrounded objects relevant to their goals, our model allows the agents to determine currently visible objects from the description of what virtual and physical objects are configured in the camera's viewing area. A degree of attention is assigned to each perceived object based on its relevance to achieve agents' goals. The agents can focus on a reduced set of perceived objects with respect to the estimated degree of attention. To demonstrate the effectiveness of our approach, we implemented an animated character that was overlaid over a miniature version of campus and that attended to buildings relevant to their goals. Experiments showed that our model could reduce the character's perceptual loads even when surroundings change.

In the recent years, with a purpose to provide visual and psychological stability to patients and hospital users, Affordance design theory based on perceptual psychological thought has been applied as hospital design. In the past, hospital service design was focused on but Affordance design theory focuses on the patients' experience and methodological research on . The characteristics of the application of Affordance design in the case of patients' experience and service point is as follows:- Firstly, Affordance design is applied when the objective of the patient's experience and the functionality of the object are combined. In other words, affordance design is a condition that arises when encounter between service contact point and patients' experience takes place. Secondly, In the field of Hospital service design, Affordance concepts in and its application can be divided on the functions of experience, cognition and sense following the application of Affordance concepts in Hospital service design. Thirdly, Affordance design method sets meaning of the action received through information provided by morphological features. The condition and surrounding has to be designed in a way that it can induce active behavior of the patient. This study has significance as it has been studied from the perspectives of Affordance theory of design psychology in addition to the physical environment of the hospital, the point of interaction between the hospital and patient, along with the elements of experience design. This study proposes the necessity of analytical study in the field of service design implementation considering various stakeholders in the service contact points of small and medium hospitals in Korea. Furthermore, study of the application of Affordance design can be complemented by reflecting the size of hospitals, the characteristics of specialties, and the specific service environment of each hospital can also be conducted.

This paper presents the efficient mechanisms for concurrency control and writing authority control in collaborative writing system are represented by the tree structures which consist of the logical objects and the content objects connected to the terminal objects of trees. For concurrency control, we adopted the approach to extend the multiple-granularity-locking-scheme. This scheme allows us to lock any objects at each level of the hierarchy. We also defined the locking compatibility table by analysing the operations applicable to any objects at each level of the hierarchy. We finally suggest the extended-multiple-granularity-locking mechanism which uses the locking compatibilility table for deciding to lock an object. This scheme gives the benefit to maximize the possibility of concurrent accessing to the shared objects. In addition, we suggest a mechanism for writing authority control which prohibits the Non-Group users from modifying the shared objects based on the concept of Group/Non-Group The proposed mechanism allows us to protect copyright very reasonably.

This paper describes the implementation of AUSV system for sonar image acquisition to survey the seabed. The system is controlled by Feed Forward PID algorithm on the vessel for bearing of the thrusters composed of motion sensor and DGPS which calculates the differences between the current location and the destination location for longitude and latitude based on GPS coordinates. As experimental results, the bearing control performance is good that the error distance from the destination positions are under 6m in total survey track of 1km. And the sonar image deviation of a object is under 12 pixels from the manned survey method, which the comparison with the total image quality is almost the same as the manned survey one. Thus the proposed AUSV system is a new method of system can be utilized at the limited survey areas as the surveyor should not be able to approach on sea surface by onboard vessel.

Transactions of updating spatial dta with mobile clients are log transactions because a user disconnected from a server surveys real features and updates them. In this environment, it is appropriate to exploit the optimistic approach based on the validation test in order to control the concurrency of transactions. On the contrary, the pessimistic concurrency control scheme makes transactions wait for a long time due to the lock. In this paper, we propose the surrogate transaction model and implement its manager for the S-S-M(Server-Surrogate PC-Mobile Client) structure which is appropriate for updating spatial data in mobile environments. In the S-S-M structure, the mobile client communicates with the server by the surrogate PC. We extend the validation condition in consideration of spatial relationships between spatial objects in this model. We also present the commit protocol where the user of a surrogate PC adjusts objects of the conflicted surrogate transaction to minimize costs for the abortion of the transaction.

This paper proposed a facial expression recognition approach using SIFT feature and SVM classifier. The SIFT was generally employed as feature descriptor at key-points in object recognition fields. However, this paper applied the SIFT descriptor as feature vector for facial expression recognition. In this paper, the facial feature was extracted by applying SIFT descriptor at each sub-block image without key-point detection procedure, and the facial expression recognition was performed using SVM classifier. The performance evaluation was carried out through comparison with binary pattern feature-based approaches such as LBP and LDP, and the CK facial expression database and the JAFFE facial expression database were used in the experiments. From the experimental results, the proposed method using SIFT descriptor showed performance improvements of 6.06% and 3.87% compared to previous approaches for CK database and JAFFE database, respectively.
