The Government has recently planned to improve the medical insurance drug price systems by removing the drug margin occurring from the difference between the official and purchasing prices, and instead by setting prices through adding drug administration casts calculated to the purchasing costs. In the circumstances, the major policy and implementing issues are how to define the drug administrance cost and how to calculate them. This study attempts to provide for the conceptional and operational definitions and thereby develop a costing model for the cost. The relationship between the current systems of medical services costs and prices were reviewed to define the concept of the costs. The study defined the costs from the narrow and wide prospective of meaning, and three operational definitions were provided. The costing model was developed applying the departmental costing principles. Finally, several prerequisites that have to be considered for the implementation of the definition and the model from the practical viewpoint.

Conclusions for the relationship between a conceptional model of stress theory and its examination based on the Oriental medicine; 1. It was considered that a general conception of stress is included into the meaning of Ki in the Oriental medicine. 2. The response-based model to stress could be comparable to a conception of Ki-pathogens interchange In the Onental medicine. 3. The stimulus-based model may be explained as a modern conception of immoderation feeling related with an internal etiological factor, specially injury of seven emotions, among three groups of etiological factors for disease. 4. The feedback conception based on the interaction model could explain the principal of reversible emotion therapy in the nine Ki. 5. In the Oriental medicine, a study to clarify a emotional etiologic factor and its pathophysiologlcal mechanism has been continued for long time before establishment of stress theory.

We propose an extended hypertext data model based on object oriented paradigm that can easily the real world and semantics. We use the BNF notation to formalize the model. In our model, We introduce conceptional navigation by associating semantics on links and drive intelligent navigation using weights on links to alleviate user disorientation problem which is currently somewhat vague. We functionally classify the hypertext node into three types:Indexing node, Content node, Extract node and likewise classify the link into Alink type, Rlink type, Slink type. We believe that the typed node and typed link approach accommodate efficient query/search in hypertext.

The purpose of this study is to establish a conceptual model of the course evaluations. in University. This paper has examined the course evaluations according to the levels, purposes, objects, and methods of them. And this paper has been classified for a conceptual model of the course evaluation. As the result of this analysis, four dimensions of course evaluation have been found. First, formative and summative evaluation have been found. The purposes of formative evaluation were improving quality of courses and collecting information for improvement of curriculum. The purposes of summative evaluation were offering informations on faculty staffing and improving of learning outcomes. Second, the levels of course evaluation were classified into university-level, professor-level, and student-level. Third, the objects of course evaluation were classified into analysis, design, development, implementation, and evaluation. Forth, the methods of course evaluation were classified into questionnaire, observation, interview, and content analysis. As a result of this analysis, 120 types of course evaluations have been found.

The study is to assist system developers or designers who are participated in the design of the user-computer interface on online services such as Online Public Access Catalogue and Online Search-ins. To design the optimal user interface, system developers and designers should try to complete the following process orderly: 1) they should know and understand the active and potential user's information seeking behaviors concerning online services in details as possible. 2) they should design the conceptional user model on basis of that knowledge. 3）They should design the logical and hierachical computer model adaptable to the current environment. 4) they should design the display of the computer terminal which is ease to learn and use by the users. 5) finally, they should design the optimal and practical user inter-face on basis of the above 2, 3, and 4.

This studied conceptional definition of digital contents and necessity of cultural contents by digital technology in progress. In addition, development process of cultural archetype digital contents based on ultimate idea and imagnation in our culture, refered from cultural archetype and digital content technology was offered by the study. Through abstraction of cultural archetype contents factor, this study deduced development model of digital contents extracted by value chain of cultural archetype contents.

The purpose of this study was to develop the environmental sensitivity(ES) measurement instrument and to apply for middle school students. The questionnaire was developed to evaluate ES. The developed questionnaire consists of 15 items in 5 categories. Each item of the instrument was developed through the conceptional analysis of the definition of ES. The 5 categories included natural environment, activity at natural environment, artificial environment, environmental pollution, environmental destruction. Data for this study were collected from 397 middle school students including 46 environmental class and 351 non-environmental class students. It was found that the developed instrument to measure ES was valid and reliable. Reliability coefficient, Cronbach $\alpha$ was 0.75. Using the developed instrument of ES, the ES was measured for the students of experimental group to which a inqury-based EE model was applied. The result was that the effect of ES of the students of the experimental group was not statistically significant. Futher research is needed related to the EE model based on the inquiry learning model and measurement of environmental sensitivity.

In this paper, Solidworks was used to do a conceptional design of an box of an electric saver in order to manufacture an electric saver having a different performance and model. Based on this, analysis was made considering weight concentrated on an box. 3-dimensional finite element analysis code, ANSYS was applied to obtain stress, strain and deformation in order to secure durability and these data was reflected to a detailed drawing.

The process of railway traffic planning is composed of several steps such as long-term, mid-term. short-term, and real-time plan. The planning of vehicle and manpower resources is a main research topic in tactical short-term planning step. Railway vehicle is usually consisted of a power car, passenger/freight cars and human resource is composed of engine driver, cabin crew, ground personnel. So far, power car was main research target in railway vehicle scheduling problem. Recently according as the light electric railway or high-speed railway is introduced, the operational planning of trainset vehicles become important, In this paper, we introduce the conceptional model for trainset restoring problem and developed heuristic algorithm.
