Soil survey and chemical analysis on mulberry nursery garden were carried out to study the causes of the non-sprouting phenomenon occured seriously in Buyeo and Ogchun in 1983 and Sangju in 1984. In addition, 115 nursery garden soils taken from 21 sapling produsers in Chungbuk province were analyzed in 1984. The results were as follows, 1. Symptom of dead saplings was the highest in boron deficiency by 59% and the lowest in rot symptom. The rest of saplings by 34.9% were not detected any symptom. 2. The nursery gardens showen non-sprouting phenomenon were located along the stream. As the result, soil depth was shallow, around 20cm deep and subsoil composed with coarse sand and gravels. 3. Nursery soils were mostly strong acid, low in Ca and Mg content, especially B, whereas available phosphorus and potassium were abundant at some gardens, and deficient at others. 4. Application of red earth or borax to nursery garden, especially to paddy, increased sprouting rate. 5. Paddy nursery garden occupied by 52.8% of 60.8ha of total garden area in Chungbuk province. Ninty point five percent of the nursery garden was lower in pH than 6.5, 87.0% lower in K than 0.5me/100g, 40.8% lower in Ca than 6.5 me/100g, 94.8% lower in Mg tha 2.00 me/100g 99.1% lower in B than 0.3ppm.

Object tracking in a real time environment is one of challenging subjects in computer vision area during past couple of years. This paper proposes a method of object detection and tracking using adaptive background estimation in real time environment. To obtain a stable and adaptive background, we combine 3-frame differential method and running average single gaussian background model. Using this background model, we can successfully detect moving objects while minimizing false moving objects caused by noise. In the tracking phase, we propose a matching criteria where the weight of position and inner brightness distribution can be controlled by the size of objects. Also, we adopt a Kalman Filter to overcome the occlusion of tracked objects. By experiments, we can successfully detect and track objects in real time environment.

국방연구개발 사업성과에 영향을 미치는 사업관리 요인에 관한 실증연구
편완주(Wan Joo Pyun),김성근(Sung Kun Kim),이주헌(John Hearn Lee) 한국데이타베이스학회 2009 Journal of information technology applications & m Vol.16 No.4
Defense R&D is an essential investment for the national security. Recently our nation has also begun to initiate a number of defense R&D projects. As a lot of fund and resources are allocated to these projects, we need to identify which projects to initiate and then how to manage these projects well. Though there have been a number of studies on R&D projects in commercial sector, there are only a few studies in defense R&D sector. Moreover, these existing defense R&D studies mainly deal with the former issues, which are occurring at the stage of project planing. We are more concerned with project management issues, such as how to manage projects that had already been evaluated to undertake at the planning stage. Specifically our study aims to identify project management factors leading to the success of defense R&D projects. Results of the empirical analysis indicate that management support, user-driven requirements management, and project planning capability are key elements for project performance.
