Healing Environment is to cure the user as a whole by considering his social, psychological aspect, beyond the functional aspect of treatment. Various design elements of healing space have been developed so far, but they were mostly described with same rank. Even though every element is significant, facilities such as nursing homes tends to run with low budget, and they can't fulfill them all at the same time. It is important to find the sequence between design elements. The purpose of this study is to reorganize the design principles of healing environment by Maslow's hierarchy of needs(Physiological needs, Safety needs, Love/Affilitation needs, Self-Esteem needs and Self-Actualization needs), and analyze elderly nursing homes and examine the framework itself by application. Research method was consist of literature review on healing space design elements and hierarchy of needs, reconstruction of design elements with hierarchy, and application on 5 Korean nursing home cases. As the result, Maslow's hierarchy of needs and design elements were linked with good balance. Analysis of 5 nursing homes revealed that lower needs were short of environmental support compared to higher needs. Especially design elements related to Physiological needs should be improved. Also, new framework had strength in not only providing gasps on current situation in detail, but also suggesting elements for improvement with hierarchy and sequence. Through this research healing environment design elements and human needs were linked. Nursing home is the last environment for the elderly, which should help to heal their body and mind and also support them to accomplish self-actualization.

As a period of pluralism, today's museum architecture has been expanding social and cultural meaning. So, Various expressions are appearing in museum architecture. Accordingly, the museum must be very reproducible and comply with aesthetic requirements. At the same time, museum construction in urban design and features must satisfy professional requirements. SANAA is one of contemporary architects has been decisively deleted existing fixed and functional layout type of program through 'The new hierarchy'. Thus, the experience of the space will vary. Now, museum space is urgently needed than ever before crustal movements. Thus, this study aims to contribute an alternative to the museum space configuration according to the trend of the times through 'The new hierarchy' of SANAA. This paper is limited to the cases of the SANAA's museum architecture. We analyze the characteristics of representation on 'The new hierarchy' appear in the museum space configuration and then, examine the value of the spatial. SANAA's 'New Hierarchy' is going to set the cognitive boundary by expression targeting plane and the surface. It is completely different than the previous boundaries. Characteristics of the expression represents non-centrality, decentrally, non-oriented, uncertainty, non-territorialization, uniformity. It is steady that identity of Space, Human, Environment in Museum. They have a relationship each concept of Independence, autonomy, equality.

Object-oriented databases (OODBs) have been adopted for managing non-standard applications such as computer-aided design (CAD), office document management and many multimedia applications. One of the major characteristics of OODBs is class hierarchy where a subclass is allowed to inherit the definitions defined on its superclasses. In this paper, I present the evaluation metrics for class hierarchy quality in OODBs. These metrics are developed to determine if a concurrency control scheme can achieve good performance or not on a given class hierarchy. I first discuss the existing concurrency control schemes for OODBs. Then I provide evaluation metrics based on structural information and access frequency information in class hierarchies. In order to discuss significance of the proposed performance metrics, an analytical model is developed. Analysis results show that the performance metrics are important factor in concurrency control performance. I consider both single inheritance and multiple inheritance. The proposed metrics can be used to provide guidelines on how to design class hierarchy of an OODB for maximizing the performance of concurrency control technique.

현 OLAP 체제에서는 모든 계층구조 스키마가 분배적으로 되는 경우에만 제대로 구현되며, 실세계에서 생길 수 있는 여러 비분배적 계층구조 스키마의 경우는 구현 불가능하다. 이전 연구에서는 집성에 있어서 현실적으로 발생 할 수 있는 모든 계층구조 스키마를 하나의 분배적 계층구조와 일곱 개의 비분배적 계층구조 스키마로 분류한 바있다. 본 연구에서는 이러한 일곱 개의 비분배적 계층구조 스키마를 분배적 계층구조 스키마로 변환시키는 기법을 제안하고 있다. 우선적으로 복잡한 비분배적 계층구조 스키마를 더 단순한 계층구조 스키마로 분할시킨 다음, 이를 분배적 계층구조 스키마로 변환시키는 것이 이 기법의 특징이다. 따라서 이 기법은실세계에서 일어날 수 있는복잡한 계층구조 스키마를 현 OLAP 체제에서 구현 가능하게끔 해준다고 볼 수 있다. 본 연구에서 제안하는 방법은 구현의 관점과 스키마 설계의 관점에서 볼 때에 유용한 방법이 되리라 생각한다.

Plant monitoring algorithm developments seem to be saturated which means that display system to show the results from the algorithm should be the well-defined and interactive tools for operator's diagnosing, controlling, restoring the abnormal plant situations. On the other hand, very little generalized display design concepts and evaluations are available. Events that are unfamiliar to operators and that has not been anticipated by designers may cause great threats to the nuclear power plant system safety operation. The abstraction hierarchy, considered most popular display design methodology but not generalized for nuclear power plant design space, has ken proposed as a representation frame work that can be adopted to design interfaces and supports operators in diagnosing overlooked events that should have been considered to operate plant safely. However most practical plant display systems do not fully stick to this design concept but partially rely on their philosophy from design experiences. Abstraction hierarchy display design concept will be do scribed and the trend of Advanced Control Room(ACR) CRT design will also be presented with the conventional display for the several type of plants. Consequently this complementary material should be of interest to designer and regulators concerned with nuclear power plant.

The purpose of this study is to investigate the psychological hierarchy structure of science concepts and to determine the effective teaching order by comparing the teaching effects of the psychological hierarchy order with those of teaching order of the current text in order to inquire validating evaluation framework of science curriculum sequence. Key concepts were selected by tasks analysis in the seven units of elementary and secondary school curriculum. Concept formation tests were developed to evaluate each concepts achievement,. The test items were made according to each of the concepts based on 12 prototype tasks developed by Frayer(1969). To identify the students' psychological hierarchy the test items were administrated to elementary and secondary school students. Ordering theory was used to identify the students' psychological hierarchy. Nonequivalent control group pretest-posttest design was used in this study as an experimental design. Teaching with psychological hierarchy order was applied tp experimental group and teaching with concept order described in the current text was applied to control group. The major results of this study are as followings: 1. The students' psychological hierarchy structures are different from logical hierarchy structures. 2. The science teachers' psychological hierarchy structures are different from not only logical hierarchy structures but also students' psychological hierarchy structures. 3. The mean score of experimental group applied psychological hierarchy order is significantly higher(p<.05) than the control group in the concept achievement.

To develop in the long view, based on context of city, the spatial program change to new spatial program that can be adopt city architectural environment. The new spatial program must have paring lot, open space, community center, which are infra structure for citizen. The needs about flexible space Increase according to complexity of spatial program. The space of absolutism, is made up hierarchy, can't accommodate complexity of spatial program. Therefore, modern architectural spaces are characterized by non-hierarchy. This research is tendency to search special quality of space program that is going complex composition according to change of modern society and modern architecture space, and analyze characteristic of inner space that have non-hierarchy to correspond hereupon.

객체 지향 설계 모델에서 클래스 계층구조는 소프트웨어 재사용성과 복잡한 시스템 설계시에 효율적이다. 본 논문에서는 래피드 프로토타입핑 기법을 사용한 객체 지향 클래스 계층 구조 설계 방법을 제시한다. 이 방법은 객체 모델링 단계에서 식별된 클래스들을 새로운 분류 방법을 사용하여 관계성 식별과 유사성을 측정한다. 여기에는 클래스의 속성과 메소드의 측정이 요구된다. 하나의 설계 모듈인 클래스 계층구조는 대화식으로 반복적인 작업을 통하여 생성되며, 각 모듈은 참조 관계, 상속 관계, 복합 관계로 구성된다. 이들 정보는 구형 및 프로그램 유지보수시에 도움을 주기 위하여 테이블에 저장하여 클래스 관계성을 그래프로 표현하고 노드클래스를 아이콘화 하였다. 따라서 새로운 클래스 추가 및 삭제 작업이 용이하여 클래스 계층 구조 재구성과 설계정보 재사용시에 효율적이다. 본 논문에서 제시하는 방법은 프로토타입 시스템으로 뿐만 아니라 실제 시스템에 최종 전환할 수 있기 때문에 시스템 분석, 설계, 구현의 능률을 높일 수 있다.
