Recently, 3D integral imaging system, which is well known as an auto-stereoscopic 3D display method, has been gaining great attention amongst researchers. The integral imaging is a promising 3D display technology since it is able to deliver continuous viewing points, full parallax, and full color view to the observers in space. In this paper, we propose a novel interactive 3D integral imaging system using a single camera. The user interface is implemented by adding a camera in the conventional integral imaging system. To show the possibility of the proposed system, we implement the optical setup and present the preliminary results. To our best knowledge, this is the first time to study an interactive 3D integral imaging.

Children seem to be more familiar with getting information from computer and internet than adults, and also it is true that information behavior in the internet has strong influences in the living of the children. When considering this fact, the public library which is the gateway to knowledge should provide a website for children services, allowing to do their life-long learning, read books and access information, without any restrains from time and space. The purpose of this study is to show the importance of public library website, especially for the children, and also to analyze trend of the country and present the solution to the problems. To achieve these goal, the analysis on the websites of the public libraries in Dagu and Gyengbuk area has been conducted. In detail, these were conducted about following criterions: existence of the website, structural system, search service, and contents.

Molecular docking is a critical event which mostly forms Van der waals complex in molecular recognition. Since the majority of developed drugs are small molecules, docking them into proteins has been a prime concern in drug discovery community. Since the binding pose space is too vast to cover completely, many search algorithms such as genetic algorithm, Monte Carlo, simulated annealing, distance geometry have been developed. Proper evaluation of the quality of binding is an essential problem. Scoring functions derived from force fields handle the ligand binding prediction with the use of potential energies and sometimes in combination with solvation and entropy contributions. Knowledge-based scoring functions are based on atom pair potentials derived from structural databases. Forces and potentials are collected from known protein-ligand complexes to get a score for their binding affinities (e.g. PME). Empirical scoring functions are derived from training sets of protein-ligand complexes with determined affinity data. Because non of any single scoring function performs generally better than others, some other approaches have been tried. Although numerous scoring functions have been developed to locate the correct binding poses, it still remains a major hurdle to derive an accurate scoring function for general targets. Recently, consensus scoring functions and target specific scoring functions have been studied to overcome the current limitations.

The purpose of this study was to better understand the tendencies and general distributive features of mathematical educational activities which are presented in the Nuri Curriculum Teaching Guidebooks. This was done by analysis of 628 mathematical activities suggested in those guidebooks, the total number of which was thirty-two. The results of this study can be summarized as follows: First, the number of activities for mathematical education was 204 for the age of three, 223 for the age of four, and 201 for the age of five. Second, these mathematical educational activities are aimed mainly for developing positive attitudes toward mathematics rather than the delivery of mathematical knowledge and skills. Third, the number of activities for developing mathematical inquiry skills was greater than that of activities for developing of inquiry attitudes. Furthermore, the characteristic of understanding the basic concepts of space and figures can be found most frequently in five kinds of activities for mathematical inquiry. Last, the activities for mathematical education are more frequently found in free choice activities rather than group activities. The results of this study also suggest that checking the current status of mathematical education for young children and the Nuri Curriculum Teaching Guidebooks can be utilized for creating teachers' manuals.

고등학교 지구과학에서 다루는 천문학 개념의 위계를 밝히고, 그에 따른 교수-학습의 효과를 알아보기 위해 지식공간론을 활용하여 학습과제 속에서 내재되어 있는 학습자의 지식상태를 분석하였다. 고등학교 학생들의 천문학적 공간개념에 대한 구성 요인 간 위계는 '공간위치 $\rightarrow$ 공간추리 $\rightarrow$ 공간변화' 순이었다. 학습자의 천문학적 공간개념 점수가 같아도 개념의 구조화( 지식상태 )가 다르게 나타나는 경우가 있었다. 이는 학습자에 따라 개별화 학습의 처방이 달라져야 함을 시사한다. 천체관측 개념의 위계는 '지구운동 $\rightarrow$ 천구좌표계 $\rightarrow$ 천체관측( 망원경 원리 $\rightarrow$ 망원경 설치 $\rightarrow$ 망원경 관측 )' 순으로 분석되었으며 2007개정교육과정에서 제시하는 순서와는 차이가 있었다. 고등학생들의 천체관측 개념에 대한 지식상태 분석에서 개념의 구조화가 잘 이루어진 학생의 경우에는 하위 위계를 이루는 지구운동과 천구좌표계, 망원경 원리에 관한 문항을 잘 맞추었고, 상위 위계에 있는 망원경 설치와 관측 문항에서 정답률이 낮았다. 그러나 개념의 구조화가 덜 이루어진 학생의 지식상태는 하위 위계를 이루는 지구 운동 관련 문항에서 더 많이 틀렸고, 최상위 위계( 망원경 설치, 관측 )를 이루는 문항에 대한 정답률이 높았다. 지구과학I의 천체관측 단원에 대하여 학습자의 심리적 위계와 교과서의 논리 위계에 따라 학습과제를 제시하여 교수-학습한 결과, 개념의 형성률은 심리적 위계에 따라 수업한 경우가 유의미( p & .05 )하게 더 높았다.

The origin of the Korean Screen Planisphere with both Traditional and New Star-Charts, made by Korean Astronomers in the Royal Astronomical Bureau of the Joseon Dynasty by adopting the knowledge of the European astronomy, is investigated by analyzing its inscriptions and star charts. The considerations on both the changes in notations or representations of names of asterisms and the naming taboos used in the Old-style planisphere imply that the star-chart is originated from either the Sukjong-Stele-Replica of Cheonsang-Yeolcha-Punyajido(天象列次分野之圖). The New style planisphere is just the reproduction of Huangdao-congxingtu (黃道總星圖), with the exception of the non-Chinese-traditional stars. The Huangdao-congxingtu was made in 1723 CE by Ignatius K$\ddot{o}$gler who was a Jesuit missionary and worked for the Bureau of Astronomy (欽天監) in the Qing Dyansty. I find that the star chart was imported in 1742 CE from the Qing by An Gukrin (安國麟) who was an astronomer in the Royal Astronomical Bureau of Joseon. The chart became model for the screen star-chart made in 1743 CE and now housed in Bopju temple. I found that the inscriptions are extracted from the sentences in both Xinzhi Lingtai Yixiangzhi (新製靈臺儀象志) and Qinding Yixiangkaocheng (欽定儀象考成). Korean historical records in either Daily Records of the Royal Secretariat of the Joseon Dynasty (承政院日記) or Annals of the Joseonn Dynasty (朝鮮王朝實錄) show that Xinzhi Lingtai-Yixiangzhi was imported from the Qing Dynasty in 1708 CE, and the Qinding Yixiangkaocheng was imported in 1766 CE. Thus, the Korean Screen Planisphere with both Old and New Star-charts was certainly made after 1766 CE.

Spectrum sensing is an elementary function in cognitive radio designed to monitor the existence of a primary user (PU). To achieve a high rate of detection, most techniques rely on knowledge of prior spectrum patterns, with a trade-off between high computational complexity and long sensing time. On the other hand, blind techniques ignore pattern matching processes to reduce processing time, but their accuracy degrades greatly at low signal-to-noise ratios. To achieve both a high rate of detection and short sensing time, we propose fast spectrum sensing with coordinate system (FSC) - a novel technique that decomposes a spectrum with high complexity into a new coordinate system of salient features and that uses these features in its PU detection process. Not only is the space of a buffer that is used to store information about a PU reduced, but also the sensing process is fast. The performance of FSC is evaluated according to its accuracy and sensing time against six other well-known conventional techniques through a wireless microphone signal based on the IEEE 802.22 standard. FSC gives the best performance overall.
