This study analyzed the situation of urban agriculture development through theories, paradigms, and typology to determine the application frequency and development keywords about space forming. The results showed that urban space by distance determines "Dimension of space forming" through self-production, public-production, and nation-social operation. Second, the complex space by shape determine "Identity of space forming" through "Flat Shape" for using the widespread land, "Compact Shape" for overcoming the small and poor land, and "Fusion of Flat Compact Shape" for systematic use between Flat and Compact. Third, building and interior space according to location determine the "Utility of space forming" through land, roof, wall, veranda, interior, and infrastructure space. The concepts about space forming of urban agriculture have an organic correlation and will be developed sustainably by the evolved cases from now on. In addition, space forming of urban agriculture produces new creation space by various fusion processes and will be a development trend of new urban agriculture.

현대의 생산환경에서 널리 사용되고 있는 생산시스템의 형태는 FMS(Flexible Manufacturing System, 유연생산 시스템)로, FMS 는 다품종 소량생산과 생산성 향상이라는 두 가지 목표에 가장 적합한 형태라고 할 수 있다. 하지만 FMS에는 시스템의 효율을 저하시키는 blocking, starving, deadlock 등이 존재하며 이들의 영향을 줄이고자 재공재고의 일시적 저장공간인 버퍼를 설치하게 된다. 시스템내의 제약으로 인해 버퍼의 총 용량은 제한적이므로, 효율적인 버퍼관리는 시스템 성능 향상을 가능하게 할 수 있다. 본 연구에서는 FMS의 각 Workstation의 작업량을 고려한 버퍼 할당을 통해 시스템 효율 향상을 추구하고, 시뮬레이션 과정을 통해 검증해 보고자 한다.

현재, 해수어와 해산 갑각류 종묘생산에 있어 해수 자치어와 유생의 초기먹이로 rotifer, Brachionus plicatilis와 B. rotundiformis를 사용한다. 또한 담수산 rotifer, calyciflorus는 담수산 자치어의 먹이로 이용이 가능하며 특히, 입이 작은 열대 관상어의 초기 먹이로 이용되고 있다. 그러나 rotifer 생산에 있어 일반적인 batch 배양 방법은 많은 공간을 차지하면서 rotifer 생산 기간 중 갑자기 전량 폐사하는 등 배양이 불안정하고 생산성을 고려할 때 양적확보를 위한 생산단가가 비교적 높다.

This study interprets Cheong-gye-cheon restoration as a process of space production during expansion of capitalism, and performs discourse analysis in order to find out that how media discourse has been related to the production of Cheong-gye-cheon space in each period of historical changes. This paper is particularly concentrating on discovering regulation in discourse which connects people's experiences and perception towards certain ways in the relationship between newly producted space and media discourse. This paper construes the period of 1960s as a process which pre-modern bodies and facilities were changed into modern and urban 'daily life' by practicing a space which splitted in a concept of time efficiency. In 1980s, media represented the facilities which had been constructed at the Cheong-gye-cheon space as a 'disqualified facilities for a center of the city'. This is because, tertiary industries were emerged at the 'Gang-nam' in this period which widen the gap of finance between 'Gang-nam' and 'Gang-Buk'. The government wanted to redevelop this space in order to function accumulating capital efficiently. Therefore shop owners nearby Cheong-gye-cheon were forced to move out. The discourse, 'disqualified facilities for a center of the city', implicates this process. The media discourse in the 2000s produced the 'myth' through the 'signifier' such as artificially flowing water, fine scenery, historical but artificial structure and etc.. However, people can experience symbols of the artificial structures which leads people to the luxurious restaurants, coffee shops, and etc.. Naturally, the spectacles produced by media direct people to the homogeneous pattern of consume. This phenomena can be explained as a process which people practice, intentionally or non-intentionally, the capitalistic mode of production which changed from a period of production to a period of consumption.

지속적인 주택공급 증가에 따라 전반적인 주택보급률은 상승하였으나 주택하위시장별로 수급이 차별화되고, 수요자의 요구도 다양해짐에 따라 주택정책의 수립에 있어서 양적정보 뿐만 아니라 지역적으로 세분화된 주택통계에 대한 질적 정보 수요가 높아지고 있다. 이중 주택공급통계(housing supply statistics)는 건축물의 건설, 사용, 수선 및 보수, 폐기의 각 생애주기(life-cycle)별로 인허가, 착공, 분양, 준공, 입주통계 등을 생산한다. 하지만 통계생산시 발생하는 누락 오기, 정보시스템의 미비 연계부족 등의 이유로 신속하고 정확한 통계 생산이 곤란한 실정이다. 본 연구에서는 이러한 문제를 해결하기 위해 시스템적 통계 생산방안을 모색하고자 주택공급통계를 중심으로 통계 및 시스템 현황을 분석하고 주택 통계와 GIS를 연계한 통합데이터베이스 구축과 시스템 정비방안을 연구하였다.

Recently, ICT environments have been increasingly developed and the pattern of the war also has been changed to NCW. The development of communication and network technology, for example, C4I and TDL(Tactical Data Link), has been prosperous and rapid. But the geospatial intelligence field which is the basis of the network frames relatively has not been developed. The purpose of this paper is to foster the geospatial governance in terms of the defense perspective. In order to do that, this paper deals with the U.S. Intelligence Community(IC) and the U.S. Army Global Information Grid(GIG), LandWarNet and those could be good examples of roles and statuses of geospatial intelligence. IC has been produced essential intelligence which is required for policymakers and military leaders. IC has several stove-piped intelligence process systems which have been separately developed and competed. And so as to complete GIG, the U.S. Army adopted LandWarNet. The U.S. Corps of Engineers organized the Army Geospatial Center(AGC) on 1 October 2009 to support LandWarNet. In order to develop NCW, we should recognize geospatial intelligence as the basis of network framework and make a central leading organization of defense geospatial intelligence. The mission of Korea Defense Geospatial-Intelligence Agency should be changed from producing GEOINT to a strategic GEOINT agency. The Army should organize a laboratory of geospatial intelligence field. The mission of producing GEOINT should be transferred to a geospatial intelligence battalion which is newly organized.

True color images display colors similar to natural colors. This has the advantage that it is possible to monitor rapidly the complex earth atmosphere phenomenon and the change of the surface type. Currently, various organizations are producing true color images. In Korea, it is necessary to produce true color images by replacing generations with next generation weather satellites. Therefore, in this study, visual enhancement for true color image production was performed using Top of Atmosphere (TOA) data of Advanced Himawari Imager (AHI) sensor mounted on Himawari-8 satellite. In order to improve the visualization, we performed two methods of Nonlinear enhancement and Histogram equalization. As a result, Histogram equalization showed a strong bluish image in the region over $70^{\circ}$ Solar Zenith Angle (SZA) compared to the Nonlinear enhancement and nonlinear enhancement technique showed a reddish vegetation area.
