Researches on integration of design and construction information from earlier era focused on the conceptual data models. Development and prevalent use of commercial database management system led many researchers to design database schemas for enlightening of relationship between non-graphic data items. Although these researches became the foundation fur the proceeding researches. they did not utilize the graphic data providable from CAD system which is already widely used. 4D CAD concept suggests a way of integrating graphic data with schedule data. Although this integration provided a new possibility for integration, there exists a limitation in data dependency on a specific application. This research suggests a new approach on integration for design and construction information, 'Product Model Centered Integration Methodology'. This methodology achieves integration by preliminary research on existing methodology using 4D CAD concept. and by development and application of new integration methodology, 'Product Model Centered Integration Methodology'. 'Design Component' can be converted into digital format by object based CAD system. 'Unified Object-based Graphic Modeling' shows how to model graphic product model using CAD system. Possibility of reusing design information in latter stage depends on the ways of creating CAD model, so modeling guidelines and specifications are suggested. Then prototype system for integration management, and exchange are presented, using 'Product Frameworker', and 'Product Database' which also supports multiple-viewpoints. 'Product Data Model' is designed, and main data workflows are represented using 'Activity Diagram', one of UML diagrams. These can be used for writing programming codes and developing prototype in order to automatically create activity items in actual schedule management system. Through validation processes, 'Product Model Centered Integration Methodology' is suggested as the new approach for integration of design and construction information.

The authors had presented two previous papers[1,2] on Helicopter/Rotorcraft develoment in Europe and US. Meanwhile, the next generation rotorcrafts, currently under development in US and Europe, have new configurations (tilt-rotor, coaxial, compound) of rotor-type vertical takeoff/landing rotorcrafts to overcome the disadvantages of traditional helicopters. For developing these new types of rotorcrafts, the upgraded conceptual design/comprehensive programs are required. In US and Europe, they are already developing new program tools with their technologies and database obtained during more than last half centuries. For us, many academia, research institutes and industrial engineers have experienced and developed core technologies on rotorcrafts (aerodynamics, structural analysis, flight dynamics, and noise analysis etc.) comparable to US and Europe during last couple of decades of developing helicopters and various configurations of rotorcrafts. In this paper, the pros and cons of conceptual design/comprehensive tools currently used in US and Europe have been summarized. Furthermore, the possibilities and problems to develope our own design and analysis tools have been studied.

고온구조물은 고온에서의 운전상태에 따라 복잡한 하중이력을 경험하게 됨으로써 상온에서 발생하는 손상 기구와는 달리 온도 의존성을 가질 뿐만 아니라, 상온에서 볼 수 없는 크립-피로의 상호작용에 의한 손상현상이 나타나게 된다. 따라서 고온 구조물의 건전성 평가를 위한 비탄성 해석을 신뢰성 있게 수행하기 위해서는 구조물의 비선형 거동을 비교적 정확히 예측할 수 있는 통합 구성방정식의 개발 및 적용과 온도에 따른 재료의 물성치 확보가 필수적이다. 본 연구에서는 통합 점소성 모델인 수정된 Chaboche 모델에 대해서 내연적 시간 적분법을 적용하여 ABAQUS의 UMAT으로 구현하였고, 개발된 프로그램을 이용하여 INCONEL 718을 사용한 단순 인장해석, 반복 소성 특성해석 및 크립 해석을 수행하여 프로그램의 신뢰성을 평가하였다. 또한 원공이 있는 평판에 대한 예제해석을 수행함으로써 개발된 프로그램이 고온구조물의 건전성 평가를 위한 비탄성 해석에 적절하게 적용될 수 있음을 확인하였다.

여러 대의 컴퓨터가 협조해야만 달성할 수 있는 응용을 위해 분산 처리 모델은 성공적인 해결책을 제공한다. 이는 분간 처리 모델이 여러 대의 컴퓨터를 통합하여 운영하는 체계적인 절차와 서비스를 제공하기 때문이다. 본 연구팀에서는 여러 대의 컴퓨터를 통합하여 활용하기 위하여 이미 익숙한 컴퓨팅 환경(단일 컴퓨팅 환경)을 위한 절차와 서비스를 적용하는 방안을 연구하고 있으며 이미 발표한 TORB(Transparent Object Request Broker)는 프로그래밍 투명성의 제공을 통하여 분산된 컴퓨팅 환경을 활용하기 위한 프로그램을 작성하는 것에 대한 투명한 서비스를 지원한다. 단일 컴퓨팅 환경에서는, 작성된 응용 프로그램을 기동하는 것이 무시하여도 좋을 만큼 간단한 절차이다. 그러나 분산된 컴퓨팅 환경에서 이를 간단한 절차로 수용하는 것은 쉬운 일이 아니며 기존의 분산 처리 모델에서는 체계적인 지원을 고려하고 있지 않다. 본 논문에서는 여러 대의 컴퓨터를 통합하여 활용하기 위하여 작성되어 분산 처리를 수행하는 응용프로그램을 단일 컴퓨팅 환경에서와 동일하게 취급하는 투명성을 제공하기 위한 방안과 이 기능의 수용에 대한 효과를 제시한다.

Objective : The purpose of this study is to explore the effectiveness of a perceptual motor program in promoting visual motor and motor control outcomes in a child with Attention-Deficit/Hyperactivity Disorder (ADHD) who is enrolled in an elementary school. Methods : The subject is 8-year-old boy who was diagnosed with ADHD but did not receive medication. Research design is a single-subject A-B-A(follow-up). Baseline and follow-up phase were 3 sessions and intervention phase were 8 sessions. After performing 40 minutes of free play on the baseline A and follow-up A, we used the copying subtest of the Korean Development Test of Visual Perception 2 (K-DTVP-2) for evaluating visual motor integration skill and the rope jumping subtest for motor skill. After providing the perceptual motor activity in intervention phase B, copying and ropejumping were performed. Results : The standard scores of the Copying for measuring visual motor integration skill were poor at an average of 4.7 points at baseline phase A, but maintained an average of 9.6 points at intervention phase B and an below average of 7.7 points at the follow-up phase A. In the Rope jumping for the motor skill, it was increased by 4.3 times in the baseline phase A and 5.9 times in the intervention phase B, but slightly decreased by 5 times in the follow-up phase A. Conclusion : This study suggests that perceptual motor program has a positive effect on visual motor and motor function of ADHD children.

This study examines garden activity and garden plant preferences for development of the garden activity program using community garden aimed for communication and integration for multicultural age. As a result, for members of multicultural society had high portion of floral arrangement and crafts, growing plants in both indoors and outdoors garden for their garden activities, and using plants for cooking, growing plants in both indoors and outdoors garden was of higher portion for native korean. In the garden plant preferences, members of multicultural society liked ornamental plants the best, due to the environmental correspondence between the plant's place of origin and their home country, while native koreans tend to prefer vegetables, reflecting the recent interest in pro-environment crops and rise in demand of urban farming, veranda gardening and weekend farming. In this study, the garden activity program for communication and integration categorized the value of garden activity into three categories; the value of respect for life, the value of consideration through caring, the value of plant ethics, based on the above preference results. The value of respect for life can be achieved by understanding the meaning of life, experiencing the will to live, and understanding the characteristics of plants and me. The value of consideration of caring comes from waiting and nurturing for living things that are different from me and adapting to the environment as a living The value of plant ethics can give us the insights for human relationships, by understanding and experiencing the natural ecosystem and plant co-existing in it. The eight-session garden activity program also went through validity verification process by experts on gardening and multiculture, and the effectiveness of the program was proved.
