Niklas Luhmann is one of the most contentious and difficult theorist in sociology but follow-up studies on his theory gradually increase for recent 10 years. The purpose of this study is to observe how follow-up studies use the difficult concepts of Luhmann. Unlike previous studies, this study adopted a keyword rather than an article as the unit of analysis because keywords are linguistic constructs that can make concepts observable. The study analyzed co-occurrence of keywords in 139 articles retrieved from social sciences category in Web of Science DB. The key findings were following: the most important keywords were the name of Luhmann(Niklas Luhmann) and theory(social systems); keywords were grouped into 4 clusters(social systems theory, systems theory, legal system and political system, the significant of Luhmann's theory from the viewpoint of the history of social theory); topic terms were systems theory, communication, Autopoiesis, risk, legal system, functional differentiation, environment, social theory, sociological theory, structural coupling, systems and evolution. The significance of the study is following: the study gives keywords as useful access point for beginners of Luhmann's theory; the study proves that content analysis by keywords network can be applied to trend analysis of difficult theoretical researches.

Despite geospatial information systems are widely used in many different fields as a powerful tool for spatial analysis and decision-making, their capabilities to handle realistic 3-D urban environment are very limited. The objective of this work is to integrate the recent developments in 3-D modeling and visualization into GIS to enhance its 3-D capabilities. To achieve a photorealistic view, building models are collected from a pair of aerial stereo images. Roof and wall textures are respectively obtained from ortho-rectified aerial image and ground photography. This study is implemented by using ArcGIS as the work platform and ArcObjects and Visual Basic as development tools. Presented in this paper are 3-D geometric modeling and its data structure, texture creation and its association with the geometric model. As the results, photorealistic views of Purdue University campus are created and rendered with ArcScene.

The study goals are establishing a library management plan for the school for the blind in Korea and also developing a structured library program, which reflected the patron's perception. We surveyed the students in three schools for the blind to identify their perception and usage statistics of the libraries. The analysis of the survey led to a school library program framework consisting of four types. To verify the applicability and effectiveness of the framework, we designed ten programs to meet the needs of the schools by consulting respective school's teachers. We administered the second survey after the classes, and we found that there were positive increases in the frequency of library use, a number of books read, perception about the libraries, amount of information used, and self-directed learning willingness.

Despite dynamical retinal image changes caused by pursuit eye movements, we usually perceive the stable spatial properties of the environment suite successfully Helmholtz and his followers have suggested that the visual system coordinates the retinal and extraretinal eye position information to represent the spatial properties of the environment. However. there have been a significant amount of researches showing that this kind of mechanism may not operate perfectly, and the pursuit eye movement employed in those researches were limited to conjugate eye movements. When an observer tracks an object moving away from the observer with his/her eyes. the two eyes rotate in opposite direction. and this kind of disjunctive eye movement may produce undesirable binocular disparities for the objects in the background. The present study examined whether the visual system compensated for the undesirable binocular disparities caused by disjunctive eye movements with extraretinal eye position information. Although the target object was presented frontoparellely to the subjects. the subjects reported that the object was slanted toward (or alway from) them in consistent with the undesirable binocular disparities produced by the disjunctive eye movements. These results imply that the visual system may not perfectly compensate for the undesirable binocular disparities with extraretinal eye position information.

Purpose: This study utilized the Geographic Information System (GIS) which is one of the representative methods for describing visual distribution, to show the distribution of visions of middle and high school students in 16 cities or provinces in Korea. Method: The data of National Health and Nutrition Examination Survey (NHANES) were analysed from 2009 to 2011 and designed a population-based cross-sectional study. The subjects were total 1,049 students at the age of 13 to 18 and uncorrected vision was provided. Male subjects were 549 (52.3%) and female subjects were 500 (47.7%). Subjects were divided into 16 cities or provinces and average vision of regions were analysed. the differentials of vision among the regions were analysed by as a spatial analysis method. Results: The average uncorrected vision were significant difference by sex (p=0.001). However male and female student groups' average vision indicated no statistically significant difference by region in those 16 cities and provinces. In order to show the differentials of middle and high school students' vision by region with a visual distribution method, the GIS was utilized for mapping. Conclusions: The differentials of vision among regions by GIS provide a visually effective distribution map.

국가 과학기술 경쟁력 재고를 위하여 R&D기관에서 생성되는 연구데이터를 종합적으로 관리하고 서비스하는 데이터 관리/서비스 시스템의 개발의 필요성이 증대되고 있다. 이에 따라 본 연구에서는 VKH (Visible Korean Human) 데이터를 3차원으로 시각화 서비스하는 플랫폼을 제안하고 구현한다. VKH 데이터는 사망과 동시에 급속 냉동한 인간의 신체를 0.2mm 간격으로 절단하며 촬영한 방대한 양의 실사 이미지 데이터베이스이며, 전통적인 생물학, 의학 분야의 연구뿐만 아니라, 현실감 있는 3D 이미지 구축을 위한 기반 데이터로 이용되고 있다. VKH 데이터 기반의 3D 데이터 시각화 플랫폼은 사용자 접근 편의성을 위하여 웹을 기반으로 구현되고, 트리 형식의 인체 구조 온톨로지와 연동하여 해당하는 인체 구성 요소를 체계적으로 관찰하는 기능, 사용자의 원하는 인체 구성 요소들만을 3D 화면에서 조합하고 관찰하는 기능, 위키피디아 백과사전을 참조하는 기능을 포함한다. 현재 인체의 머리 부분 3D 데이터를 대상으로 플랫폼이 구축되고 있으며, 향후 전체 인체를 대상으로 서비스할 예정이다.

Graphic thinking for the idea sketches brings about variations between abstract realm and concrete one, and between conceptual realm and perceptual one. When design information is projected to the thinking process, some images are generated, and transformed. We reviewed the sketching devices for computerization to deal with a lot of design data in the computing environment. The LCD Tablet can be a substitute for the Pen & Paper to get rid of irksome tasks at handling the design data. Using a protocol analysis technique, we examined the influences of different design information, which is consisted of verbal concepts and/or visual images, and abstract information and/or concrete one. The findings show that there are no significant differences of influences between verbal/visual information and abstract concrete information at the conceptual design. These facts support that graphic thinking process is progressed with the perceptual and mental image.

웨이블릿 변환은 영상을 위치 정보와 주파수 정보를 가지고 표현함으로서 다른 변환 방식과는 큰 차이를 보여준다. 웨이블릿 변환된 2-D 영상은 인간의 시각 체계(Human Visual System)에 적정한 양자화 및 부호화를 위한 계층적 구조를 제공한다. 인간의 시각이 민감하게 감지하는 성분은 정확하게 부호화하고 다른 성분은 적절한 정보의 손실을 적용하는 원리를 이상적으로 적용할 수 있다. 이런 웨이블릿 변환의 통계적 특성을 이용한 제로트리(zerotree) 부호화 기법은 영상 전체에서 의미 있는 계수를 선별하여 약속된 우선 순서대로 부호화함으로써 매입파일(embedded file)을 생성한다. 본 논문에서는 Shspiro 가 제안한 EZW(embedded Zerotree wavelets) 알고리즘을 개선하여 화소 단위가 아닌 블록 단위로 부호화 함으로서 좀더 나은 성능을 가진 알고리즘을 제안하였다.
