WTO 정부조달협정 건설서비스 양허하한선 인하시의 건설시장 변화와 대응방안
문혁,김명수 한국건설관리학회 2009 한국건설관리학회 논문집 Vol.10 No.3
건설서비스 양허하한선 인하 문제는 국내 중․소 건설업체의 이해관계와 밀접하게 연관되어 있는 바, 국내 관련 제도 및 건설시장에 미치는 영향에 대한 세부적 분석이 필요하다. 특히 중․소 건설업체를 위한 ‘지역제한입찰제도’ 및 ‘지역의무공동도급제도’ 등에 영향을 미치고, 궁극적으로는 이들 업체의 수주시장에도 변화가 예상되므로 이에 대한 사전적 검토가 필수적이다. 그러나 이러한 양허하한선을 낮출 경우 우리나라의 건설산업에 어떤 영향을 미치는지에 대한 연구는 없는 실정이다. 따라서 본 연구에서는 건설서비스 양허하한선 조정으로 인한 실제 수주시장의 변화를 전망해 보고 그 실질적인 효과를 분석하여 ‘건설서비스 양허하한선 인하’ 문제에 대한 기본 입장 정립의 근거 자료를 제시하고자 한다. 현재 WTO GPA의 적용을 받는 우리나라의 양허하한선은 정부발주공사의 경우는 500만 SDR(74억원)이며, 지자체와 기타공사의 경우에는 1,500만 SDR(222억원)이다. 정부는 지방자치단체 및 공기업 등 기타기관의 건설서비스 양허하한선에 대하여 ‘지역의무공동도급제도’ 등을 고려하여 높은 수준을 유지하는 것이다. 우리나라의 지방정부기관 및 공기업의 건설서비스의 양허하한선은 일본과 함께 현재 1,500만 SDR로서, 여타국의 500만 SDR에 비해 월등히 높게 설정된 상황이며 최근 미국을 중심으로 EC 등 주요 회원국은 지방정부기관 및 공기업의 하한선을 외국의 경우와 같이 500만 SDR로 인하할 것을 요구하고 있다. 분석결과 이러한 500만 SDR로의 개방 확대는 ‘07년 기준으로 총 2조 105억원 규모의 시장이 축소되어, 이는 지역업체들에게 부담을 줄 것으로 예상된다. 지역업체들의 수주 비중은 규모가 작은 공사일수록 높아지므로, 총 2조 105억원 규모의 시장감소(공동도급 1조 6,802억원, 단독도급 3,407억원)는 지역업체 수주활동에 적지 않은 영향을 미칠 것으로 분석된다.

It is impotent to identify the causative agents of abortion in equine for minimizing the loss of breeding costs in equine Industry. Recently, the abortion has often occurred in equine herds and thus the purpose of the study was aimed at the identification of equine herpesvirus-1, one of the frequent pathogens to abortion, using polymerase chain reaction. Six fetuses to be aborted at nine to ten months in pregnancy reared in six herds were used in the study. Two primers in the PCR were made from glycoprotein B gene of EHV-1. The primers specific for EHV-1 amplified 1880 bp of PCR products from DNA extracts from thorax fluids, livers, lungs, and spleens of four in six aborted fetuses. Consequently, PCR could be applied to diagnose the abortion of EHV-1 and also confirmed to play a major role of the viral pathogen associated with equine abortion in Jeju island.

In recent years, many franchised rice cake cafes which transformed Korean traditional food into modernized one have emerged. Therefore, It seems to be needed to research how different they are from others in producing interior design. At this point, this study surveyed present state of rice cake cafes in Gwangju and analyzed the character of their interior. First, franchised rice cake cafes provide two sections: a place for display and for enjoying food and beverage. Second, the essential elements in producing interior of three brands among franchised rice cake cafes were surveyed from the spacial, decorative, esthetic point. Third, as they are the places where sell traditional food, rice cake, they typically prefer traditional image but it depends on each brand in expressing the image. Not like "A day of rice cakebo' which emphasize its traditional image, the other two brands, "Bizzen' and 'Yedason' have modern image. In the process of producing the interior of franchised rice cake cafes, we need to produce global interior design by accepting the trend and distinguishing from the normal cafes.

Moving object segmentation from a nonstationary camera is a difficult problem due to the motion of both camera and the object. In this paper, we propose a new confidence-based background subtraction technique from moving camera. The method is based on clustering of motion vectors and generating adaptive multi-homography from a pair of adjacent video frames. The main innovation concerns the use of confidence images for each foreground and background motion groups. Experimental results revealed that our confidence-based approach robustly detect moving targets in sequences taken by a freely moving camera.

One of the main applications of digital image processing is the estimation of the number of certain types of objects (cells, seeds, peoples etc.) in an image. Difficulties of these counting problems depends on various factors including shape and size variation, degree of object clustering, contrast between object and background, object texture and its variation, and so on. In this paper, a new automatic colony counting algorithm is proposed. We focused on the two applications: counting the bacteria colonies on the agar plate and estimating the number of seeds from images captured by smartphone camera. To overcome the shape and size variations of the colonies, we adopted the distance transformation and peak detection approach. To estimate the reference size of the colony robustly, we also used k-means clustering algorithm. Experimental results show that our method works well in real world applications.

The purpose of this study was to investigate the perception of the polarization in the construction industry. Three factors were identified as the reasons of the growth polarization: the change of construction business, structure of construction supply chain, and sales and technical capacity of the construction enterprise. Based on these factors, qualitative indicators were developed to investigate the perception of the growth polarization according to the enterprise scale and business structure. Most of the surveyed companies reported that they had experienced declining the growth rate. The degree of the rate was much larger in small and medium enterprise. And there was difference between general contractors and prime contractors in presenting the cause and solution of the polarization.
