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.

본 논문은 기존의 하이퍼텍스트 시스템의 문제점을 모델링 능력 미약 및 방향상실(lost in hyperspace. Disorientation)문제를 최소화 하기 위하여 데이터 모델을 확장하고 이 확장된 모델이 객체지향 데이타베이스 시스템에서 표현되는 방법을 BNF 정의를 사용하여 형식화하였다. 본 제안 모델은 모델링 능력 향상 및 개념적 항해를 위하여 링크에 의미를 부여하고, 노드와 링크를 기능에 따라 여러 타입으로 분류하여 효율적인 항해가 되도록 하였으며, 하이퍼텍스트 시스템에서 가장 문제가 되는 방향상실 문제를 방지하기 위하여 구조를 강화시키는 방법과 지능적인 항해 방법을 제안하였다.

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.

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.

본 논문은 기존의 전력절감기(Electric Saver)와 성능과 형상이 다른 전력절감기를 제작하기 위하여 SolidWorks를 활용하여 전력절감기함의 기초설계를 실시하였다. 기초설계를 바탕으로 전력절감기함에 하중이 집중되는 부분을 고려하여 해석하였으며 외함의 내구성을 보장하기 위하여 3차원 유한요소해석 코드인 ANSYS를 이용하여 응력(stress), 변형률(strain), 변형량(deformation)을 구하였으며 이를 제작에 사용된 상세설계에 반영하였다.

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.
