This study aims at evaluating the spatial configuration of general hospitals in terms of Visitors' movement pattern. In doing so, the study deals with three hospitals which are recently built and are generally considered to show recent trends in their spatial configuration. First, the Space Syntax method is used in order to systematically describe and analyse the spatial configurations, and thus to find out the spatial characteristics of each hospital in terms of movement pattern. Second, the spatial characteristics reflected on the 1st floor plan are compared with the planning concepts considered at early stage of the design. It can be said that the concept of hospital street and the spatial hierarchy should be carefully taken into account and tested the spatial configuration by the completed floor plan in order to satisfy the planning concepts.

This paper is to develop the position error equations including the attitude errors, the errors of nadir and ship's heading, and the errors of ship's position in the free-gyro positioning and directional system. In doing so, the determination of ship's position by two free gyro vectors was discussed and the algorithmic design of the free-gyro positioning and directional system was introduced briefly. Next, the errors of transformation matrices of the gyro and body frames, i.e. attitude errors, were examined and the attitude equations were also derived. The perturbations of the errors of the nadir angle including ship's heading were investigated in each stage from the sensor of rate of motion of the spin axis to the nadir angle obtained. Finally, the perturbation error equations of ship's position used the nadir angles were derived in the form of a linear error model and the concept of FDOP was also suggested by using covariance of position error.

The purpose of this study is for providing the people with the objective method which estimates the various spatial configuration of primary schools in terms of teacher's screening through analyzing structural visual aspects of common classrooms and open corridors for multi-service of primary schools in Korea. In doing so, the study makes use of graphical solutions derived from the concept of 'Frame' which is one of Basil Bernstein's theories. As a case study, it deals with five primary schools designed for open-education. Throughout this investigation, it takes some numerical values of spatial characters concerned with 'Frame', and can have some conclusions about the relationship between the change of curriculum and the spatial configuration.

The purpose of this study is to suggest the design guidance of education facilities by analysing Alvaro Siza's education facilities of which considered having idiosyncratic spatial characteristics. Focusing on the his planning of learning and transitional space of education facilities, this study aims at eliciting the spatial characteristics of his architecture. In doing so, this study tries to figure out his basic method of reification of his basic architectural concept which is articulated in learning space and transitional space of education facilities by introducing the boundary element and penetration of light in order to support student's learning activity and foster abundant cognitive experiences. Therefore, this study presents the feasible supplementary design method for future education facilities to be appropriate not just for quantitative factors, but for qualititative aspects such as user's psychological fulfillment, and emotional satisfaction.

This study attempted to compare usability of auditory interfaces, which is a comprehensive concept that includes safety, utility, effectiveness, and efficiency, in personal computing environments: verbal messages (speech sounds), earcons (musical sounds), and auditory icons (natural sounds). This study hypothesized that verbal messages would offer higher usability than earcons and auditory icons, since the verbal messages are easy to interpret and understand based on semiotic process. In this study, usability was measured by a set of seven items: ability to inform what the program is doing, relevance to visual interfaces, degree of stimulation, degree of understandability, perceived time pressure, clearness of sound outputs, and degrees of satisfaction. Through the experimental research, the results showed that verbal messages provided the highest level of usability. On the contrary, auditory icons showed the lowest level of usability, as they require users to establish new coding schemes, and thus demand more mental effort from users.

The authors map some of the current Business Models in the Massively Multiplayer Online Player scenario. These maps represent Value Creation Systems by resorting to Value Net constructs and notations, and are offered here as a proof of concept and utility. The authors claim that these mappings can enable readers, managers and IT experts, to build new insights onto such Business Models and develop requirements for Information System infrastructure. When approaching the Value Creation System as a Value Net the goal is to think outside the conceptual box of Value Chains and understand how the different activities interact, by exposing the multiplicity of value types and flows. In doing this study the authors are attempting to synthesize a new Business Model proposal that could underlie the development of an infrastructure for the collaborative creation, distribution and exploration of online massively multiplayer games, beyond the traditional producer-consumer roles.

There has been much concern and worry about executing school curriculum from the year 2000 because the seventh curriculum is based on the complicated' differentiated education' concept. Now the new textbook has been developed according to the curriculum. This paper will reinforce the understanding of the curriculum and textbook in school math. In order to do this, this paper will present questions on three subjects to help school teachers and people related to math education to probe and discuss the benefits and problems of teaching math using the new textbook. The three subjects are based on the contents included in certain chapters of the math textbook. These are 1) understanding mathematics concepts using manipulatives or concrete objects, 2) doing math projects or problem solving activities 3) learning mathematics using calculators. furthermore, it is emphasized in this paper that math teachers must keep in mind that they should execute instruction in their own way using the 'textbook' not as a bible but as a guideline.

Community involvement is to be the keystone of primary health care, Unfortunately, efforts to promote it failed in many countries. Author inquired into the reasons why such efforts fail, and the alternative strategies for effectively promoting it in Korean situation today. In doing so, the concept of community involvement is clarified as an amalgamation of two different concepts; one is that of the community development, and the other is that of approaches for overcoming the alienation of the people from the health care process. Stategies of community involvement in Korea so far followed the line of the community development, e.g. village health worker. It loses, however, the feasibility as Korea has experinced so cial and economic developpment. The strategies of the second line of thought is now more feasible; empowering the people by providing more information and enhancing comitment to health, improving acceptabilty of community involvemt on the part of the health professionals and the bureaucrats, and building the mechanism of community involvement into the health policy-making process.

Spam mail is one of the side effect of the development and improvement of the internet that restrains the privacy of the individual on line. However indiscriminate application of Spam mail blocking can also cause significant violation on freedom of doing business to the fluent commercial transactions on line. Therefore this research looks at the exact understanding of the concept of Spam mail and inquiry on Its issues. Also it looks at the case studies of its institutional solutions in USA and Europe as well as the advantage and disadvantage of the case studies on its technical solution. Finally, the research inquires into overall prevention of Spam mail, which considers both technical and institutional soiution. With this research, limitations of current Spam mail prevention system and technology are pointed out and more effective course of overall Spam mail prevention solution is studied.
