The Intelligent Space is a space where we can easily interact with computers and robots, and get useful service from them. In such a space, location information is very important, since the agents cannot provide proper service to a proper person at a proper location without location information. Our positioning system uses CCD cameras. It is important to decide where to arrange the cameras for the best localization depending on the tasks in the space. How to arrange cameras for the best localization is discussed in this paper.

As public space such as plaza and square in the compact city type multi-use complex is a social public space that various communication and cultural exchange take places in city environment. The purpose of this study is to analyse and categorize the design elements as a valuation basis for the public space in the compact city type multi-use complex. The scope of contents of this study is focused on the Central City, COEX and Western Dome facilities in Korea. This study review based on the previous studies and statistical analysis about questionnaires obtained from 131 users of three facilities were conducted for this study. The results of the survey as follows accessibility, comfort, exchange were extracted as the aspects for evaluation for functional activity and connection, openness, hierarchy were extracted as the aspects for evaluation for space formation. The K facility's priority aspect is the accessibility and the S and the W facilities' are the openness.

For the company, the office space is the expensive resource next to human resource. Employees are under the influence of physical characters of the office space. Among them lighting is the most effective factor in physical, biological and psychological for employees. Although there are lots of investments in architectural aspect of the office space, there is almost no investment and consideration about the lighting environment. Therefore this study was trying to find out these things as follow. First, evaluate lighting environment of people who works in the office spaces. Second, find out which factors are more affective in evaluation of lighting environment. And then with these findings this study found what should be considered as important in lighting planning of the office space. As the result of this study, however the majority of the employees are satisfied with current lighting conditions, they are not satisfied with individual operation of lighting. And in office space work type and position changes by age can affect in a large degree more than other factors. Therefore when planning lighting of the office space, it is necessary to figure out work features of Individual and group exactly and accept the difference by positions appropriately.

The purpose of this study was to suggest appropriate human model for ergonomic evaluation considering working postures on 3D space. Background: Traditionally extreme design rules have been widely utilized at the stage of designing products. Body size of 5th percentile and 95th percentile in stature has been generally selected for controllability and clearance evaluation, respectively. However, these rules had limitations in reflecting working posture in ergonomic evaluation. Method: In order to define working posture on 3D space, not only sagittal plane but also lateral plane was considered. Kinematic linkage body model was utilized for representation of working posture. By utilizing the anthropometric data of 2,836 South Korean male populations, the point cloud for end points of linkage models was derived. The individuals who were lacking in certain controllability were selected as human models for the evaluation. Result: In case of standing posture it was found that conventional approach is proper for all controllability evaluations. Contrary to standing posture, tall people had less controllability on control location below shoulder point in sitting posture. Conclusion: From the derived proper range on controllability, ergonomic evaluation rule was suggested according to working posture especially in standing and sitting. Application: The results of the study are expected to aid in selection of appropriate human model for ergonomic evaluation and to improve the usability of products and work space.

현대사회의 복잡다기한 문제파악과 분석을 위해 최근들어 다양한 변수를 바탕으로 하는 복잡계 분석의 도입이 활발해 지고 있다. 외래부의 공간배치에 따른 환자들의 공간인지와 사용성을 미리 예측하는 것은 질 높은 병원서비스 제공을 위해 매우 중요한 요소라 할 수 있다. 객관적 분석을 위해 노인의 질환별 표준프로그램 절차 및 분석을 위한 지표를 마련하고 히트맵 분석과 정량적 분석을 통해 대기공간의 균일성을 평가하였다. 이에 본 연구에서는 요양병원을 대상으로 복잡계 분석 방법을 이용하여 진료공간 접수공간 상담공간의 배치변화에 따른 4개 대안의 대기공간 균일성을 분석하기 위해 73개의 셀을 설치하여 시뮬레이션을 구축하고 그에 따른 밀도를 도출하였다. 연구를 통하여 다음과 같은 결론을 얻을 수 있었다. 1)대기공간의 전체 공간밀도는 접수공간의 배치가 가장 큰 영향을 미친다. 2)검사공간과 진료공간의 확실한 분리배치가 대기공간의 균일성을 높여주는 방안이다. 3)접수공간의 위치가 입구에서 가까울수록 대기공간의 밀도균일이 커진다. 마지막으로 본 연구는 대기공간 균일성 평가에 이산사건 시뮬레이션의 적용방안에 관한 연구로서, 행위자기반모델이 공간분석 방법론으로서의 활용과 평가에 활용도를 가질 수 있음을 입증하였다.

In this paper, we describe the installation of VLBI Correlation Subsystem (VCS) main product and its performance at the Korea-Japan Correlation Center (KJCC). The VCS main product was installed at KJCC in August 2009. For the overall performance evaluation of VCS, playbacks, Raw VLBI Data Buffer (RVDB) system, and Data Archive (DA) system were installed together. The VCS main product was connected between RVDB and DA, and the correlation results were put into the DA to confirm the normal operation of VCS 16 station mode configuration. The evaluation test was first performed with 4 station mode, same as the factory test of VCS main product. Based on the results of 4 station mode, the same evaluation test was conducted for 16 station mode of VCS. We found that the correlation results of VCS were almost similarly compared to those of the Mitaka FX Correlator. Through the test results, we confirmed that the problems such as spectrum errors, delay parameter processing module and field programmable gate array errors in antenna unit, which were generated at the factory test of VCS main product, were clearly solved. And we verified the performance and connectivity of VCS by obtaining the expected correlation results and we also confirmed that the performance of VCS was sufficient for real VLBI observation data in both 4 and 16 station modes.

본 논문은 공공공간의 개선 방안을 위하여 고려되어야 하는 평가 지표를 도출하고 공무원/학계 및 실무자 측면에서 중요도를 비료/분석하고자 하였다. 이를 위하여 공공공간의 특성에 따른 계획항목을 선행연구를 바탕으로 도출하고, 세부지표들을 선별 후 전문가그룹인터뷰(FGI : Focus Group Interview)를 통하여 도출과정의 적합성과 도출된 항목들에 대한 부적합 여부를 논의하고, 합의된 항목만을 선정하였다. 선정된 지표는 전문가 설문을 통한 계층적 의사결정법(AHP : Analytic Hierachy Process)을 실시하여 중요도를 분석하고 종합순위를 도출하였다. 연구 결과, 공공공간의 중요도는 실무 전문가의 경우 사용성, 공공성, 환경성, 연계성, 정체성, 공간성 순으로 나타났으며, 공무원/학계는 사용성, 환경성, 연계성, 정체성, 공간성, 공공성 순으로 나타났다. 또한 종합분석 결과 우선순위에서 실무 전문가는 안전성을 가장 중요한 요소로 인식했으며, 공무원/학계는 청결성이 가장 중요한 요소로 나타났다. 본 연구에서 도출된 결과는 향후 공공공간의 개선 방안을 위한 계획적인 고려사항 및 평가로 활용될 수 있는 지표로 활용될 수 있을 것이며, 공공공간의 디자인가이드 라인으로 제시될 수 있다.

고 신뢰성을 요구하는 우주, 군 등과 같은 응용분야에 집적회로 사용에 대한 필요성이 증가하고 있다. 따라서 상업용(Commercial Off The Shelf) 집적회로부품에 대한 신뢰성 보증 요구조건과 실험규격에 대한 연구가 매우 필요하다. 본 연구에서는 ECSS(European Cooperation for Space Standardization) 품질규격과 MIL-STD-883(집적회로 시험방법)을 기초하여 상업용 집적회로부품의 신뢰성 검증(evaluation)을 위한 스크린(Screening) 실험방법을 검토하였다. 그리고 상업용 부품에 대한 스크린 시험절차와 검사방법을 제안하였다. 또한, 제안한 시험절차와 방법에 맞추어 상업용 Linear Bipolar 집적회로를 평가하였다. 시험결과 상업용 Linear Bipolar 제품이 고 신뢰성 활용을 위한 신뢰성 요구조건을 모두 만족하는 것을 확인하였다.
