Recently, stereotactic radiosurgery plan is required with the information of 3-D image and dose distribution. A project has been doing if developing LINAC based stereotactic radiosurgery since April 1991. The purpose of this research is to develop 3-D radiosurgery planning system using personal computer. The procedure of this research is based on two steps. The first step is to develop 3-D localization system, which input the image information of the patient, coordinate transformation, the position and shape of target, and patient contour into computer system using CT image and stereotactic frame. The second step is to develop 3-D dose planning system, which compute dose distribution on image plane, display on high resolution monitor both isodose distribution and patient image simultaneously and develop menu-driven planning system. This prototype of radiosurgery planning system was applied recently for several clinical cases. It was shown that our planning system is fast, accurate and efficient while making it possible to handle various kinds of image modalities such as angiography, CT and MRI. It makes it possible to develop general 3-D planning system using beam's eye view or CT simulation in radiation therapy in future.

The objectives of this study were to investigate the perceptions of Korean female university students for clothing pattern tendency and structural element of clothing pattern image dimension and to find how individual personality type influence the preferred clothing pattern characteristics. For this study, a questionnaire was designed and sent to 600 female university students of Daejeon, Seoul and metropolitan area. The tool used in this study was MBTI(The Myers-Briggs Type Indicator) Form G Korean version and for the analysis of data SPSS 10.0 package were used. 10 representative patterns for this study were floral, dot, stripe, check, animal, abstract & artistic, geometric, vegetable & leaf, paisely, patchwork pattern. The data were analyzed by factor analysis, arithmetic mean, One-Way ANOVA, x²-test. The major findings were as follows: Clothing pattern image dimension perceived by Korean female university students for 10 representative patterns were basic form, deluxe, specialty, and cultural dimension. Among them, basic form and deluxe dimension were major dimensions. In basic form dimension, dot pattern score was high indicating female students perceive it as light, comfortable, clean, cool and simple pattern image. In deluxe dimension, floral pattern scored high and in specialty dimension, abstract and artistic pattern scored high among other pattern image. In cultural dimension, geometric pattern and check pattern scored high. Based on other detailed analysis results, It is concluded that the personality type greatly influence clothing pattern evaluation. For example, in case of color combination of patchwork pattern, there was a difference in color preference depend on a personality type such as sensing(S) or intuition(N). Therefore, sensing personality type preferred adjacent color combination than contrast color combination. Detailed marketing strategy is necessary in planning textile design of merchandise plan.

최근 3D 이미지 스캔(image scan) 작업을 통해 획득한 3D 포인트 클라우드(point cloud)를 활용하는 사례가 점차 많아지고 있다. 특히, 도시나 건물 차원의 실내/실외, 기계 플랜트 등 3D 공간정보 콘텐츠를 활용한 서비스 개발 필요성이 증가하면서, 3D 이미지 스캔 기술의 수요가 급격히 늘고 있다. 기존의 3D 이미지 스캔 방법을 사용하는 경우, 이미지 스캔 작업은 노동집약적인 수작업으로 진행되는 것이 일반적이다. 따라서, 사용자가 복잡한 설비로 이루어진 공간을 스캐닝 할 때나, 사용자가 내부로 진입하기 어려운 좁은 공간을 스캐닝하기에는 어려움이 있으며, 결과적으로 그림자 영역 문제로 인한 품질 저하 문제를 발생시킨다. 본 연구는 사람이 진입하기 어려운 영역에 스캐너가 장착된 로버를 활용해 이미지 스캔을 하는 방법을 제안한다. 스캔 경로를 정확히 제어하기 위해, 로버 이동 규칙 정의 기반 3D 이미지 원격 스캔 자동화 방법을 기술한다. 이 방법을 통해, 사용자는 로버의 스캔 경로를 규칙 기반으로 정의함으로써 3D 스캔 계획을 자동화할 수 있다.

본 연구의 목적은 대학교육 환경에 변화속에서 교육 서비스품질이 학생만족, 대학이미지, 몰입 그리고 충성도에 미치는 영향을 파악하여 양질에 대학교육을 위한 전략적 방안을 제시하고자 함을 목적으로 한다. 이를 위해 수도권 소재 대학 4학년에 재학중인 학생 229명을 표본으로 6개의 가설을 설정하고 실증분석을 하였다. 연구의 결과는 교육 서비스품질이 만족과 대학 이미지에 긍정적인 영향을 미치고, 만족은 몰입과 충성도에 영향을 미치는 것으로 나타나고 있다. 그러나 이미지는 몰입에는 영향을 미치지 않는 것으로 검증되었다. 몰입은 충성도에 영향을 미치는 것으로 나타났다. 가설검증 결과를 통해서 교육 서비스품질 향상을 위한 대학에 노력이 대학이미지와 충성도에 영향을 주고 장기적인 대학의 경쟁력 향상을 가져 온다고 할 수 있다. 교육 서비스품질 관리를 위한 궁극적인 노력이 급변하는 대학환경에서 생존하는 방법을 제시해 줄 것이다.

Recently, many vision-based navigation methods have been introduced as an intelligent robot application. However, many of these methods mainly focus on finding an image in the database corresponding to a query image. Thus, if the environment changes, for example, objects moving in the environment, a robot is unlikely to find consistent corresponding points with one of the database images. To solve these problems, we propose a novel navigation strategy which uses fast motion estimation and a practical scene recognition scheme preparing the kidnapping problem, which is defined as the problem of re-localizing a mobile robot after it is undergone an unknown motion or visual occlusion. This algorithm is based on motion estimation by a camera to plan the next movement of a robot and an efficient outlier rejection algorithm for scene recognition. Experimental results demonstrate the capability of the vision-based autonomous navigation against dynamic environments.

The increasing concern over radiation exposure in the nuclear industry has fostered agrressive efforts to reduce the levels of radiation exposure. One area of the effot to reduce the radiation exposure is the development of a remote radiation monitoring system. Remote radiation monitoring can serve many benificaial functions reduce exposure to radiation by plant personnel, impruve the quality of the data that is collected and recognize the radiation environment easily. Radiation mapping system gives a good information that represents radiation level distribution. The system we have developed consists of a data acquistion parts, mobile robot and remote control parts. Data acquisition parts consist of radiation detection module and vision acquistion module which collect radiation data, visiion data and distance information. In remote control parts, the acquision data are processed and displayed. We have constructed radiation mapping image by overlaying the vision and radiation data. The radiation mapping techniques for displaying the results of the survey in an easily comprehendable form will facilitate a better understanding of the radiation environment in the facility. This system can reduce workers radiation exposure and aid to help work plan, so it has significant benifits in cost and safety.

The purpose of this project is to greatly elevate the image of a high-technology wireless communication company by improving its office space environment through remodeling techniques. In order to accomplish this goal, the design concept was established in the direction of harmonious beauty with maximized functionality and aesthetics. Specifically, an efficient traffic line was planned in consideration of the connectivity between mutual spaces, and smooth yet strong formal aesthetics was given to such things as planes, frontal surfaces, and ceiling design, so as to do away with the existing authoritarian atmosphere and create an image of a futuristic company.
