In this paper, we propose a method generating of instance ontology from web pages for the lodge. First, we analyze non-structured web documents and generate information extraction rules in order to extract specific informations from web sources. And we extract the informations from various web pages related to lodge using generated rules. And then ontology instances are automatically generated through adding OWL semantic information to the extracted informations. Our method is able to cut down on time and cost than a method which generates various ontology instances manually. Also agents can search the information corresponding to semantically what the user needs in the various web pages using numerous vocabulary having same meaning and provide good quality of informations to user.

Neural networks are works are used in the framework of sensor based tracking control of robot manipulators. They learn by practice movements the relationship between PSD(an analog Position Sensitive Detector) sensor readings for target positions and the joint commands to reach them. Using this configuration, the system can track or follow a moving or stationary object in real time. Furthermore, an efficient neural network architecture has been developed for real time learning. This network uses multiple sets of simple back propagation networks one of which is selected according to which division(corresponding to a cluster of the self-organizing feature map) in data space the current input data belongs to. This lends itself to a very training and processing implementation required for real time control.

본 연구는 초등과학교육에서 홀리스틱 교육방법을 적용했을 때 전통적인 교육 방법과 비교하여 인지적인 면과 정의적인 면의 차이점과 영향력을 찾아내기 위한 연구에 그 목적이 있는 바, 그 연구 결과에 따르면 아래의 결론을 얻는다. 초등과학교육에서의 홀리스틱학습에 적용한 영향에 따른 검사를 통한 학습 성취도 조사에 의하면 분명한 변화는 없으나 창의적 사고 증진과 과학적 태도에는 의미 있는 영향이 있고 긍정적인 변화를 보여주고 있다. 따라서 학생들은 다양한 경험을 통한 홀리스틱 학습에 의해 과학교육에 흥미와 새로운 욕구를 가지게 되고 이것은 정의적인 목적에 도달하는데 매우 영향력이 있음을 보여준다. The purpose of this study is to find out the difference and effectiveness on cognitive and affective aspect comparing with traditional education method when the holistic education method is applied in the elementary science. As the result of the study, following conclusion is obtained. There was no evident change in learning accomplishment investigation through test paper in the holistic learning application effect in primary school, but it showed effective and positive change in creative spirit improvement and scientific attitude. Therefore let the student have interest and new desire on science education by the holistic learning through various experience and it is very effective to reach affective goals.

In this study, we study about park and ride facilities at subway station in seoul, since we have perceived that park and ride facilities at subway's station's serious problem on its operation and usage. We practiced the interviews and transfer rate survey so found these problems of operation usage problem, spatial utilization, private park and ride facilities. Through the analysis of these problem we propose the adequate alternatives and we hope that our study contribute operation rationalization of park and ride facilities at subway station.

Objective : Since a lot of assessment tools for depression have been developed and used, it is difficult to choose the proper and optimal instruments for the purpose of their usage, In order to maximize the effectiveness of assessment for depression, this paper reviewed the characteristics and specific features of currently using tools. Method : The domestically and internationally using assessment tools for depression were reviewed and classified by litera-hire search and clinical experience. Results : Methods of assessment, selecting guides and characteristics of assessment tools for depression were presented. Conclusion : This paper would provide helpful guidelines for selecting the assessment tools. We suggest that it is needed to develop the assessment tools for depression that reflects Korean specific culture and custom.

Objective: The purpose of this study was to compare the difference in three dimensional tooth movement using three different wire sizes (0.018 × 0.025-in, 0.016 × 0.022-in, 0.016-in) on a NiTi scissors-bite corrector. Methods: Computed tomography (CT) images of the experimental model before and after tooth movement were taken and reconstructed into three dimensional models for superimposition. The direction and the amount of tooth movement were measured and analyzed statistically. Results: The lingual and intrusive movements of the crown of the maxillary second molar were increased as the size of the NiTi wire increased. The roots of the maxillary second molars moved buccally except for the 0.016-in group. The intrusive movement of the roots of the maxillary second molars was increased as the size of the NiTi wire increased. Due to the use of orthodontic mini-implants, anchorage loss was under 0.2 mm on average. Conclusions: The 0.018 × 0.025-in NiTi wire was most effective in lingual and intrusive movement of the maxillary second molar which was in scissors-bite position. Indirect skeletal anchorage with a single orthodontic mini-implant was rigid enough to prevent anchorage loss. 본 연구에서는 NiTi scissors-bite corrector를 세 가지 서로 다른 굵기 0.018" × 0.025", 0.016" × 0.022", 0.016" 의 NiTi 와이어로 제작하였을 때 각각의 치아 이동 양상을 치아 이동 시뮬레이션 장치인 Calorific machine을 이용하여 3차원적으로 분석하고자 하였다. 가위교합에 이환된 상악 제2대구치 모형을 제작하고 제2소구치와 제1대구치 사이에 교정용 미니 임플랜트(orthodontic mini-implant)를 식립하여 제1대구치에 간접골성고정원을 설계하였다. 세 가지 굵기의 NiTi scissors-bite corrector를 부착하여 실험하였다. 치아의 이동 전후에 실험 모형은 computed tomography (CT)로 촬영하고 3차원 데이터로 변환하여 중첩하였다. 치아 이동 방향과 이동량을 계측하여, NiTi scissors-bite corrector 와이어 굵기에 따른 치아 이동 양상에 관한 통계적 유의성을 검정한 결과, 제2대구치 치관의 설측 이동량은 0.018" × 0.025"군(2.65 mm)이 가장 많았으며, 0.016"군(1.96 mm)과 통계적으로 유의한 차이를 보였다(p < 0.05). 제2대구치 치관의 압하량은 0.018" × 0.025"군(2.35 mm), 0.016" × 0.022"군(1.18 mm), 0.016"군(1.00 mm)으로 0.018" × 0.025"군이 나머지 두 군과 유의한 차이를 보였고 (p < 0.05), 치근의 압하량은 0.018" × 0.025"군(4.19 mm), 0.016" × 0.022"군(3.29 mm), 0.016"군(2.24 mm)으로 세 군 간 모두 통계적 유의차를 보였다 (p < 0.05). 치아의 이동 양상을 관찰한 결과, 0.016"군에서는 제2대구치 치근의 협측 이동이 나타나지 않았다. 간접골성고정원으로 사용된 제1대구치의 고정원 소실은 0.2 mm 이하로 나타났다. 이상의 결과를 토대로 0.018" × 0.025" NiTi 와이어로 제작한 NiTi scissors-bite corrector를 교정용 미니 임플랜트를 이용한 간접골성고정원과 함께 이용하였을때, 최소한의 고정원의 소실과 함께 가장 큰 상악 제2대구치의 설측 이동 및 압하가 일어났다고 할 수 있다.

As the science education is increasingly playing a important role for the future, many teaching methods are investigated so that the students can participate in science education with interest and concern. The purpose of this study is to introduce the space and future unit which is underdeveloped in the education process of elementary science. This study was carried out as follows : 1) The contents of science education are composed of the experience which the students can easily acquire in the daily life. 2) The cooperative learning and holistic approach education were taken as teaching methods. This study suggests that the unit, which can give the students faith and confidence about the space and future, and the new teaching methods oriented to students such as the cooperative learning and holistic approach education, should be applied to the open education in practical and effective way.
