We construct a four-level system where a metastable state is included in an $Er^{3＋}$ Doped Yttrium aluminum garnet (YAG) crystal. Because of the action of the coherent field, the traditional light amplification with inversion can be exhibited with remarkable variation. As a result, we propose a method to achieve the gain equalization by atomic coherence. At the same time, we find that the high index of refraction accompanied by vanishing absorption can also be reached in this model. We also find that a higher index of refraction with zero absorption can be easily obtained when the coherent field is off resonance.

This research is intended to analyze the tendency and mixed-use of the PFI for the middle schools in Chiba Province, Japan. The Ichikawa 7th middle school has included food supply system, nursery school, auditorium, day service center and care house. It consists of 2 PFIs. The one is middle school, food supply system, nursery school and Auditorium. The other is Day Service Center and Care House for elderly. This is the first mixed-use school by PFI in Japan. The PFI is a very nice tool for the future of our educational environment. But it has weak points, too. This paper analyze the case of Japanese PFI for the better results of Korean BTL systems.

The purpose of this study is to define the altenative assessment and to suggest the method of scoring system. Alternative assessment includes any type of assessment in which student create reponses to a question rather than choosing a responses form given list( as for multiple choice, true/false, or matching). Alternative assessment can includes short answer questions, essay, performances, oral presentation, demonstrations, exhibitions, portfolios, and etc. To evaluate the each type of assessment, we can apply the method of holistic scoring and analytic scoring system. Also we have to concern the type of scoring mechanism directly relate to what we want to assess, our purpose for assessment fitting into the educational enterprise. Before applying the alternative assessment in our classroom, we need to step back and reconsider all our design features and teachers' responsibility.

The recent trend has been consistently raised by the media of educational environment issues such as deteriorated existing school facilities, water-leaks due to the lack of proper maintenance and poor toilet facilities. For the efficient use of the budget to be used for maintenance of school facilities, an effort to extend the life of the facility to the max is needed. However, current maintenance system of school facilities is to deal with the defects after discovered, and consequently the durable period is shortened due to early deterioration of facilities and efficient budget execution cannot be realized. For this reason, the result emphasizes the need to improve maintenance management system of school facilities, and proposes a systematic bill of school facilities maintenance according to expert investigation and correlation analysis through school facilities maintenance-related information that is distributed to a number of laws.

평생교육 종합정보시스템은 국민들 누구나 자신이 원하는 정보에 접근할 수 있도록 평생교육에 대한 Guide 역할을 수행하는 평생교육 포탈사이트 구축을 목표로 하고 있으며, 나아가 평생교육의 'Information', 'Learning', 'Communication', 'Business' 창구로서의 역할을 하고 있다. 그러나 현재 이러한 비전을 수행할만한 시스템 설계 원리나 구체적인 기능들에 대해서는 논란이 되고 있는 것 같다. 이에 한국교육개발원 평생교육센터에서는 평생교육 체제에 관한 국민들의 요구를 반영할 새로운 시스템을 설계 중에 있다. 이 글은 이런 목표를 담당할 시스템의 설계에 관한 이론적인 접근이다.

The purpose of this study is to attain basic source for spacial re-organization of the elementary school. This is the first step of some series of the study, For purpose, some investigations is to grasp the change of education system, curriculum and the present condition of institution were done, and some questions on the using condition of space, the satisfaction and the hope for the space of their school were asked to 371 teachers in elementary school, by questionnaire and interview methods. The result of the survey was analyzed using a statistics-analysis program SAS. The results are summarized as follows: 1) Corridor is using to extend of learning and living space. 2) To correspond to open education, various comers are placed in the classroom and the corridor. 3) As the change of educational system, teachers need parting the source center and the teacher's room.

Educational programs for promoting occupational safety and health have widely been established in advanced countries, such as United States and Germany, in the area of disaster prevention Focused attentions and investments for safety and health education have been placed especially for small and medium sized companies. Recently, information technologies have also been applied for the development and management of educational programs in those countries. It is also worth noting that a wide variety of incentive systems has been implemented for managers and workers to voluntarily Participate in safety and health education. Based on the brief survey on incentive systems in advanced countries, this study proposes two different incentive models, such as 'Supervision Exemption Model for Participants in Safety and Health Education' and 'Compensation Program fur Educational Expenses and Losses', which may efficiently be employed in Korea. These incentive models may contribute to revitalizing the occupational safety and health education which has recently been dwindled due to the changes in governmental regulations.

There have been many suggestions of ontology-based semantic web service systems and recommendation systems, but there has been no attempt to study educational consultation. Thus this study set out to tackle the problem and design specialized service to reflect individuals' interest, aptitude, hobbies, and grades based on the semantic web technology so that they could search the related information easily by managing personal profiles and identifying the meanings between information. It also aimed to suggest a convenient information service system of personalized educational consultation.

Education is the largest application area of adaptive hypermedia systems. The user modeling is considered a very important part of the field of adpative hypermedia systems. In this paper we present the developed user model which provides different educational contents using a neural network. The user model has been verified on hypermedia for learning about basic web concepts, multimedia and HTML. This paper reports the results of simulation. Our simulation shows that the user model exactly can provide contextual different links for different students.

It is necessary to the development of the best maintenance system for applying the long-term maintenance plan using the cost breakdown structure in the educational facilities. This study developed the cost breakdown structure for the best maintenance system using the delphi method. For the convenience of maintenance, the maintenance cost breakdown structures are separated into building exterior wall, building inside wall, electric installation, heating installation and outdoor facilities. And these results atomized in each parts. And this study constructed the cost breakdown structure to maintenance's practicality and effectiveness through the expert analysis.
