The primary questions addressed by this research are the followings: Have the OPAC interfaces of children's libraries been designed user-friendly; What difficulties have OPAC searchers experienced in using OPACs; How do they perceive the system after searching it; Through the answers of those questions the problems of OPACs for children as searching tools have been grasped and recommendations have been suggested in order to improve the OPAC interfaces. An experiment was conducted and 28 children of grades 4 to 6 performed 5 searching tasks. The searching behavior of OPAC searchers has been analyzed thoroughly. The data of their perceptions about the system was collected through a questionnaire after completing the tasks.

The purpose of this study is to find important personal characteristics that affect search process and outcome, and to formulate causal models about searching behavior, by examining the channels and the magnitude of the factors identified. The study was designed to conduct a quasi-experiment with 67 student subjects. A total of 29 elements concerned with aptitude, personality, formal education, effectiveness of online training, search process, and search outcome are measured and reduced to 9 variables. 12 hypotheses were tested statistically and path analysis was done to investigate causal relationship among variables. Finally 5 models were formulated.

Today, apartment is the most common residence type and various behavior occurs in living room space of apartments. Active usage of living room in modem life increases user's desire of wanting a better environment and leads to find various methods such as remodeling. At the point when considering moving or remodeling, this study focuses on the change of lighting color as it is one of the methods for initial stage with moderate price. As living room is easily influenced by lighting, providing active environment to support inhabitant's behavior through the use of various lighting sources will cut down unnecessary remodeling costs and may be the most simple method to actualize lighting environment for inhabitant's behavior. To give change with the least effort, change in artificial lighting environment was attempted with combinations of lighting color and switching on lights according to illuminating location. This study suggested the capability of changing lighting environment of previous living room area by exchanging lighting sources in lighting equipment in order to satisfy the required behaviors of inhabitant.

본 연구는 미국 텍사스 주의 소도시에 있는 스캇 앤 화이트 클리닉의 외부공간을 대상으로 하여 외래환자와 방문객들이 직면하는 길찾기의 문제점을 분석한다. 연구의 공간적 범위는 클리닉의 외부공간으로 한정하여 진입도로에서 진입하여 주차한 후 출입구에 도달하는 경로에서 관찰되는 행태적 특성을 분석한다. 분석의 초점은 진입도로에서 이루어지는 경로선택의 결정과 그것이 클리닉에 진입하기 위한 출입구 결정에 미치는 영향관계에 둔다. 분석은 외부공간에서의 길찾기에 관한 기존 연구문헌을 참고하여 작성한 연구모형에 의해 이루어진다. 구체적으로 보면, 이용자들이 보이는 날씨, 성별, 그리고 나이에 따른 길찾기 행태의 차이를 클리닉의 남동측 출입구와 남서측 출입구에서 발생하는 이용자들의 하차 빈도를 측정하였다. 또한 하차의 위치를 행태 지도에 기록하여 연구모델에 나타나는 상관성을 분석하였다. 길찾기 행태분석 결과를 통해 파악된 외부주차장에 주차한 후 클리닉에 접근하는 이용자들의 경로선택의 문제점과 클리닉의 입구 공간에서 하차한 이용자들의 입구선택에서 나타나는 문제점을 토대로 하여 외부공간에서 발생하는 길찾기 행위의 효율성을 증진시키기 위한 디자인 추천 사항을 다음과 같이 제시한다: (1) 시각적 단서를 제공하기 위해 남서쪽 출입구의 형태와 색채 차별화; (2) 도로에서 클리닉 진입공간에 위치한 안내판의 글자 크기 확대; (3) 학습된 길찾기 행태를 보조하기 위해 동쪽에 랜드마크 시설물 설치 및 목적 지점의 최종경관 개선; (4) 과도한 클리닉의 정보에 의해 감소되는 가독성을 고려하여 안내판의 정보 간략화; (5) 색채의 대조를 고려(출입구 벽에 설치된 클리닉의 이름이 갈색에 푸른색으로 설치되어 있어 색채의 대비가 낮아 가독성 떨어짐); (6) 클리닉 중앙 출입구의 하차 공간 상부에 설치된 캐노피 기둥의 과도한 크기에 의해 발생하는 가시공간의 감소에 의해 발생하는 하차 공간 사용의 혼잡 문제를 제거하기 위해 기둥규모 축소; (7) 하차점 6까지 캐노피를 확장하여 우천시에 발생하는 공간 사용의 문제점 제거; 그리고 (8) 올바른 하차공간 사용을 위해 진입 접근도로에 차선 설치.

본 연구의 목적은 상황 인식 위치 기반 서비스를 위해 정성적인 개인 공간 행동을 포착하는 새로운 방법을 제안하는 것이다. 단순한 추적이내 사람의 위치 변화에 대해 색인 생성을 넘어서서, 사람과 환경 사이의 관계 변화가 본 연구의 공식 모텔에 대한 기본 소스로 간주된다. 특히 이 연구는 특정 지역의 경계 근처에서의 사람의 움직이는 행위에 중점을 둔다. 그 행위를 포착하기 위해 그 개체의 영향력 범위를 적용하는 새로운 접근 방법이 제안된다. 이러한 개체 시공간적으로 확장된 점는 그 영향력 범위를 그 개체의 위치와 함께 잠재적 사건이내 상호작용 구역으로 간주한다. 이렇게 포착된 정성적 공간 행위는 알려진 지역 근처의 개체 관계의 더 정제된 설명을 제공하여 단순한 공간정보 제공을 넘어선 실시간 공간 의사 결정 지원 시스템 강화에 도움을 줄 수 있다.

Indexing images using traditional indexing methods like taxonomy is not always efficient because of its visual content. This study examined how to apply folksonomies to image retrieval. To do this, first, we developed a category model for image tags found in Flickr. The model includes five categories and seventeen subcategories. Second, in order to evaluate the usefulness of the model to represent the various image tags as well as to investigate the end-user tagging behavior, three researchers classified the sampled image tags(141 most popular tags, 105 tags on three individual tag clouds and 3,848 image tags assigned on 156 images) according to the model. Finally, based on the research results, we proposed three methods for efficient image retrieval: extending folksonomies by combining them with ontologies; improving image retrieval efficiency using visual content and folksonomies; and updating taxonomy using folksonomies.

Proposed in this paper is the intelligent video surveillance system to effectively detect multiple loitering objects even that disappear from the out of camera's field of view and later return to a target zone. After the background and foreground are segmented using Gaussian mixture model and shadows are removed, the objects returning to the target zone is recognized using the chromaticity histogram and the duration of loitering is preserved. For more accurate measurement of the loitering behavior, the camera calibration is also applied to map the image plane to the real-world ground. Hence, the loitering behavior can be detected by considering the time duration of the object's existence in the real-world space. The experiment was performed using loitering video and all of the loitering behaviors are accurately detected.

This design study was conducted to plan and propose the bus-station as the public design for Cheongju City. The study was provided other purposes which designed its function as plant container and revealed the brand identity of Cheongju City, Jikji. At planning stage, design plant container with motif from top roof of the Early Printing Museum of Cheongju. And planed it located on the top of facility. The facilities, with design factors that increase satisfaction, were planed through the analysis of user behavior. The narrow frame and transparent wall were intended to establish clear sight for its users or pedestrians on road. In order to harmonize with urban surroundings, decreased the fanciness of designed figure and used achromatic color as lead main color.

This research is an introductory study that hopes to interpret the cultural scenic landscape by analyzing Korea's mountains, streams, topography, color, light, human behavior, and more based on real landscape paintings. It places its purpose on understanding our intrinsic cultural scenic landscape by investigating the changed topography and the differing life patterns caused bythe active national land development after the modern era. With Seoul, which is now difficult to find images of its past, and the surrounding areas of the Han riverbed, the interpretation related to its original topography, landscape, climate, weather, and human behaviors was observed while the main focus was placed on the climate of the perception held by people regarding Mt. Geumgang and other ranges which are not fully opened to the public yet. In order to comprehensively analyze the figures of features and appearing landscapes including color, light, and more, it was described through the concept called climate. Hereupon, the real landscape paintings by Gyunjae(Jeong-Seon), mainly bearing features of existing Korean mountains, wereutilized as visual historical material. However, not having all his works, other pieces with representative characteristics were utilized such as "Gyeong-Gyo-Myeong-Seung-Chup(a painting with picturesque sceneries around old Seoul)" and "Hae-Ak-Jeon-Shin-Chup(a landscape painting including even the spirits of the seas and mountains)" which contain the regions' distinct scenery. As a result, the old cultural scenic landscapes of Korea are regarded as containing diverse mountains and where the conceptions of the treatment of mountains were reflected.
