공간과 형태 디자인에 있어서 스터디모델은 완성될 공간이나 형태가 디자인되는 공간과 형태에 구체적인 시각적 매개체를 제공하며, 보다 근본적으로 디자인도면에 대한 상호 보완적 수단으로서 이용된다. 즉 스터디모델은 2차원적인 속성을 지니는 디자인 도면에 3차원적인 이해 수단을 추가적으로 부여한다. 따라서 디자인이 진행되는 동안 구체적인 공간의 형태와 공간구성을 디지털스터디모델을 이용하여 자유로운 각도에서 시각적으로 감지하며 공간과 형태를 분석하게 해준다. 일반적으로 유형적인 재료를 사용하여 제작되는 스터디모델은 디자인 과정에서 디자인 내용의 변경과 스터디모델의 용도에 따라서 여러 번 제작되어야 하며, 디자인도면과 모델의 관계는 공간의 지각과 이해를 통해서만 이루어진다. 이것은 디자인도면과 스터디모델 매체사이의 상호보완성이 동시에 이루어지지 않기 때문이다. 그러나 본 연구에서 제안된 3차원 디지털 디자인 프로세스를 이용하면, 즉각적인 시각적 표현과 더불어 디자인 단계에서 다양한 분석과 디지털 디자인모델 결과물들을 얻어낼 수 있게 된다. 결국 디자인계획과 디자인 구체화 단계에서 디지털디자인 프로세스를 활용할 경우 입체적 표현을 실시간으로 적용할 수 있으며, 3차원 디지털모델을 시각화하여 최종 디자인을 위한 공간과 형태의 다양한 분석이 가능하게 된다.

Suburban green space is an important component part of urban ecological system, the third largest space between urban center and peripheral countryside. Because of the specific regional location of the suburban green space, it differs from the green space in the center of the city in the respects of construction and planning. Anyhow, it has the features of less investment, quicker efficiency, free and easy management and good ecological effects. The writer of this paper holds that urban ecological construction should be planned rationally and laid out in an overall way under the prerequisite of making full use of and protecting local species so as to further extend the green ecological space at urban periphery, to create dense green surroundings, and to explore a way for ecological construction to develop in a scientific, effective and healthy way.

The objective of this investigation is to establish a simple yet effective block adjustment procedure for the orthorectification of multi-orbit satellite images. The major works of the proposed scheme are: (1) adjustment of satellite‘s orbit accurately, (2) calculation of the error vectors for each tie point using digital terrain model and ray tracing technique, (3) refining the orbit using the Least Squares Filtering technique and (4) generation of the orthophotos. In the process of least squares filtering, we use the residual vectors on ground control points and tie points to collocate the orbit. In orthorectification, we use the indirect method to generate the orthoimage. Test areas cover northern Taiwan. Test images are from SPOT 5 satellite. Experimental results indicate that proposed method improves the relative accuracy significantly.

Commercialization and privatization of outer space has been developing to the extent that public space law regime established at the UN seems to be somewhat incompatible with the today' s commercial launching services. Thus, this paper analyzes, at first, the UN space treaties to specify the obstacles for promoting commercial use. The necessity of some covert amendment of UN treaties is suggested through the national space legislation. Then three state practices are examined to propose a new concept of the "launching state" including the Sea Launch project, since the concept of the "launching state" is of the major importance to enact an effective national act to better accommodate UN space treaties to the present necessity.

Application of space technology in the field of communication and remote sensing becomes increasingly important in human life. Advancement of communications means shinks the size of our globe and that of remote sensing techniques improves the quality of human well-being. It is a world trent for each country to make its best effort in advancing its capabilities in these fields sometimes independently and other times jointly with other nations. Korea being no exception to this world trend is planning various starategies in application and development of space technologies. However, unfortunately, Korea is a new commer in this field. Statellite Technology Research Center (SaTReC) of Korea Advanced Institute of Science and Technology (KAIST) initiated to aquire satellite technology by sending its graduates abroad in 1989. As a result KITSAT-1 was launched in 1992 and KITSAT- 2 was launched in 1993 and they became Korea's first two satellites in orbits. Academic program including On-the Job-Training for Korean students at the University of Surrey, UK, is also an innovative scheme of mixing education and practical know-how for successful technology transfer, which resulted in a small but very capable and effective satellite experts group in Korea for self-propelled research and development in space activities. In this context, space development strategy should be considered in terms of the following factors; (1). Participation in international space activities as an active member to utilize international organization and to contribute to the peaceful use of space, (2). Development of national defence structure for independent activities in space, (3). Enhancement of manpower utilization for space development and promotion of national pride and (4). Education of youngsters for the extension of intellectual activities into the limitless space. In order to make very costly space development project most efficient, governmental level space development organization directed by the head of nation should be established and should manage all space development programs making full use of its all available resources including the advantage of the university based R&D capability.

A study of facility securement and space utilization at national universities in Korea was conducted in order to help develop an efficient model for space management at national universities going forward. For the study, 36 national universities were asked to submit answers to a questionnaire on usage of campus facilities in 2013. We then analyzed the results of space management for the 27 universities that participated in the questionnaire in each of the past three years (2011-2013). Lastly, we conducted an awareness test on the space utilization policies and space management for these universities. The results are as follows. First, the aggregate average score for space utilization over the past three years is 74.06. The annual average score increased year-over-year and then decreased; it was 69.44 in 2011, 80.68 in 2012, and 72.05 in 2013. A decline in the sense of responsibility of universities to effectively manage space appears to be a factor in the decrease. Second, with 53% of respondents in agreement, treatment of campus area as private space appears to be the biggest hurdle for efficient space management. As such, a plan to foster a more communal view of campus facility area is required. Third, resistance from constituents to existing guidelines for space allocation on campuses appears to be limited (78.1% of respondents answered the guidelines currently in place were average, satisfactory, or very satisfactory). We believe this result points to a mutual understanding forming amongst constituents regarding guidelines on space allocation on campus.results of satisfaction research: the users are generally satisfied with education and student.
